finds integer of comma separated thousands anywhere in string (,{0,1}|[0-9]{1,3})+  no decimal at end but it could be copied from your example above

This regex does not work as it should. You are missing a '\' before the '.'
Like this: ^(((\d{1,3})(,\d{3})*)|(\d+))(\.\d+)?$
Otherwise something like 100,000,0 will match.
