[CentOS] CentOS 7.x Russian certification

Dear all,

does anyone have any idea where to get a list of all CentOS 7.x versions
that are certified to be used within Russia.
My guess is that organizations, such as FSTEK, TR-CU declares those
versions/distributions of CentOS that are certified to be used with
commercial projects in Russia.

Anyone with some information on this, plase advice, I would be very
grateful.

Regards,
Gorazd
