which matches the line start (
^– you may not need this), thenFS, then a digit\d5 times{5}, then the line end$(again, you may not need this, but you’d then have to protect against a sixth digit following).You don’t specify which language/regexp, but the above is pretty generic.
EDIT: You can provide word boundary markers instead of line start/end markers, which is a little more generic.
\bwill mark a word boundary (in Perl – see Perlre – but equivalents exist in other languages)
