[DUG] Checking bank account numbers

[Ross Levis]

I worked that out many years ago for my last employer.  At that time most of
main banks used the same algorithm but there was 3 or 4 oddball ones.
 
I still have the routine I wrote in Dataflex, but I don't think I can
legally provide it since I'm still under a loose agreement with the
employer.

But I can tell you the bank numbers of those using different algorithms to
the main banks.  Those were 08, 25 & 33, and 29.  25 & 33 used the same
algorithm.

Cheers,
Ross.

The actual algorithm varies with each bank, so you need to contact all
the banks that you intend to support in regards to checkdigit checking.

Contact your local bank, they can supply you with an algorythm that
you can use to check if a number is correct.

I assume it has a checksum or hash in it somewhere. But I know not
where.
