   1.                                                   Please revise the cover
page of your prospectus to clearly disclose the number of

   2.                                                   Please refer to our
prior comment 6.
                                                            We see as part of
your revised disclosure, you indicate that the yearly revenue
                                                            assumptions
provided by Keystone were independently verified by Check-Cap
                                                            through Check-Cap
s own due diligence, which was performed on the Israeli
                                                            operations of
Keystone, as well as through part of the legal and financial due
                                                            diligence performed
by Check-Cap   s advisors. Please tell us how and to what extent

              Check-Cap    independently verified    information related to
Australia that was
              provided by Keystone.
                If Keystone does not have any specific market potential reports
for Israel and
              Australia as standalone countries, tell us your basis for the
assumption that with its
              Implant and Bio product lines, Nexus products and
customer-centric approach,
              Keystone will be able to grow sales and revenues in these
regions.
                We do not see where you have explained what "an analysis of the
competitive
              landscape    entails, the significant material assumptions
underlying revenue
              projections and the limitations specific to this analysis.
                We see your disclosure that if the company is unable to
maintain any of its current
              regulatory approvals or obtain such new regulatory approvals,
that may have an
              impact on Keystone   s projections, although each such case would
need to be assessed
              to determine what (if any) impact it has on the plan and the
impact on the projections
              if it is not obtained. Revise to explain each specific regulatory
approval assumed in
              making the projections and the specific impact if those approvals
are not obtained.
                Lastly, we see your revised disclosure that 'the financial
projections include assumed
              capital expenditures (including fit-out for new space and
equipment to meet the
              expected increased demand in each location) for Keystone   s
Israel, Irvine and
              Australia facilities to be expended over the course of the plan.'
Revise to disclose the
              expected amounts of capital expenditures and tell us how those
are included in your
              projections.
3.       Please refer to our prior comment 7 and tell us where your revised
disclosure clarifies
         which elements of the projections were provided by Keystone and which
were prepared
         by Check-Cap. In this regard, you state at the bottom of page 134 that
the following
         assumptions indicate the changes that the Check-Cap board made to the
projections
         provided by Keystone and list several bullet points which appear to be
general in nature,
         i.e. 'revenue projections were modified on the basis that comparable
companies grow at a
         rapid pace in the first 6-7 years'. Revise your disclosures to
specifically explain how the
         projections were changed by the Check-Cap board.
4.       We see your response to our prior comment 13. Your disclosure does not
address how you
         considered all of the uncertainties regarding your projections in your
conclusion that you
         can reasonably provide projections for the next ten years. Please
advise.
5.       Please refer to our prior comment 16. Please tell us if any companies
of like size and stage
         were considered by Variance and if not, why not.
6.     We note your disclosure in footnote 1 that "projected R&D amounts are
subject to the

department." Revise

7.       We note the disclosure that "Projections based on historical average
revenues per direct
         sales representative are helpful in a genuinely mature business
model." Revise to define
         your use of the term "genuinely mature business model" and clarify
this is a belief of
         management.
