POST /v1/t/cvr_dk_validate

unprobed

Offline validator for a Danish CVR-nummer (8-digit business registration number issued by the Danish Business Authority). Normalizes input to digits only, checks length and computes a modulus-11 checksum using weights 2,7,6,5,4,3,2 on the first 7 digits compared against the 8th check digit. Result is flagged as best-effort since some legacy CVR numbers do not conform to the checksum rule.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
