You can qualify that line with:

/^((?:\D|^)\d{5}){8}$/m

Demo

Or

/^((?:-|^)\d{5}){8}$/m

To be more specific with hyphen delimiters.

Try this

  string source = @"25686-47362-04822-08149-48999-28161-15124-63556";

  bool result = Regex.IsMatch(source, "^[0-9]{5}(-[0-9]{5}){7}$");

Explanation:

  ^               anchor (beginning of the string)
  [0-9]{5}        5 digits group
  (-[0-9]{5}){7}  7 more groups of 5 digits
  $               anchor (ending of the string)

You can use this:

^\d+\.\s(\d{5}-?){8}$

It matches a whole line that matches your criteria: A digit or more, a dot, a whitespace, 8 blocks à 5 digits with hyphens.

I am not sure there is a way to ask for it to "repeat" the grouping, but i would type it like that:

/^([0-9]{5}\-[0-9]{5}\-[0-9]{5}\-[0-9]{5}\-[0-9]{5}\-[0-9]{5}\-[0-9]{5}\-[0-9]{5})/
