NHS number check
GET /v1/check/nhs checks that a value is 10 digits and that the last digit matches the NHS modulus 11 rule.
This is not a live NHS Spine or PDS lookup. A passing checksum does not prove the number was issued to a real person.
The example 943 476 5919 is the published NHS Digital test number.
