NINO checksummed ?

Not to my knowledge.

Staff at NI HQ always denied to me when I worked there that there was any such checksum. Not surprising for a system devised in the 1940's, long before computers. The first two (alpha) characters can give some indication of age, but that's more or less it, as far as I'm aware.

(VAT numbers are, however).
