Thank you, I'm working on integrating this into stdnum.

In general it is very difficult to "guess" a checksum algorithm,
especially because there are so many possibilities. I have done that a
few times when I had some hints on what the algorithm might be like and
had a large testing dataset.

Some more-or-less official source and some numbers to test against are
the best way to ensure that you have a correct implementation.

Do yo have any public references to the structure of the number that I
can refer to? Also do you happen to have some numbers that I can use
for tests? Ideal would be a test-set of around 100 numbers that ensure
that the algorithm is correct in most corner cases.

Kind regards,
