      It’s not possible because that’s 16 digits.

            What if they are generated in base 16, but numbers containing a-f are discarded. Did you think about that? Huh?

              Yes. The check digit is calculated using base 10

            Seems to be correct, I was thinking of a different card in my wallet.

            Everything is in base 10 (unless it’s in unary).
