That said, it should be emphasized that the GUID really is a 128-bit number and could be represented in a number of different ways.

Where "Magic Numbers.default Guid" is just "an empty" all zero Guid "00000000-0000-0000-0000-000000000000".

I think val == UUID(uuid_string) would work the best.

No need to get .hex() or do any string replacements.

The specified digits are assumed to be the low order digits of the group.

When you look at the Guid constructer code it doesn't use regex. Easy to modify the above regex to meet the requirements of the original question.It includes all the regexes required to validate different versions of UUID's plus you get various other functions for validation.Information regarding the origin and location of the exception can be identified using the exception stack trace below.[Invalid Operation Exception: Request format is unrecognized.] System.
