Might as well map 'A' to 0. 2021-10-19T20:02:01+00:00 Abigail abigail@abigail.be 2021-10-19T20:02:01+00:00 3f9069255c9ab3f2a600ce465fa08e2cb2edc57d The SEDOL specification says 'A' maps to 10, 'B' to 11, etc. However, to perform a checksum, all we care about is module 10 arithmetic. So, whether 'A' maps to 10, or to 0, doesn't matter.

Last character of a SEDOL must be a number. 2021-10-19T18:25:58+00:00 Abigail abigail@abigail.be 2021-10-19T18:13:33+00:00 210e271ec3014cf6f08e9ce5d3e2ffbd92a61619 Without this check, it could validate the SEDOL which uses a letter as a check digit. For instance, if the check digit is a '1', using 'B' would validate as well.
