Project mention: Take a break: Error-detecting codes in credit card numbers, ISBNs etc. (2000) | news.ycombinator.com | 2024-03-07Memories. About 12 years ago I looked in to this stuff as part of adding national checksum support to an IBAN library. It was quite a mission to discover the number of systems out there, most of which were insufficiently documented or undocumented. Wound up reverse engineering quite a few of them (period braindump available[3]).
In the end I wrote a function[1] which reverses an input known to fail a checksum to determine probable transcription errors based upon a manually compiled, exhaustive list of probable mistranscriptions[2].
