This is not right place. Repomd.xml contains expected checksum of
comps-epel7.xml which you should check. E.g. on client
$ cd /var/cache/yum/x86_64/7Server/epel7-centos7-x86_64/
$ grep -B2 comps repomd.xml
<data type="group">
  <checksum type="sha256">4d64c5d0ca2636e265629906a57962e5b15b719b0f80ed6f593eb7ed49d5eaf4</checksum>
