For CentOS you can do: 

rpm -q centos-release | cut -d. -f 1 | cut -d\- -f3- | tr '-' '.'

(Yes, ugly.  Works fine, however.)

I've not tried on a RHEL box but exchanging redhat-release for
centos-release probably will work there as well.

Depending on contents of /etc/*-release is problematic as it's just a
pure text file that can, and often is, modified by the user.
