In search of a Modulus 10 script

Does anyone know anywhere when I could download a working version of the modulus 10 formula?

I've already tried a few places, but so far all the scripts I've checked out seem to give out error messages.

I did this in ASP a few years ago. It was rather simple. Although I don't have the code. Where are you getting stuck at? Have you tried coding the algorithm from scratch? If I remember correctly, it was only about 5 or 7 lines of ASP JScript code which would probably be about the same in PHP. Although its been a while and I might be thinking of some other code...

I'll see if I can find the algorithm and see if I can build it from scratch.

Have you looked at this:

Mod 10 in class flavor... The article probably does a better job of explaining then I could.
