I find that strange: you don't know what the steps are but you suspect additional steps. My suggestion is that you do some research first and then ask again.

kind regards,

Confused. You are talking about purely mathematical steps, and not any steps dependent on look up tables? So you are looking for the steps besides, call up the server and ask if the credit card number is valid, correct?

What are the steps that you know and what additional steps do you suspect?
