Hi,

 thanks for finding and fixing this. Also for catching the typo.

I really do not like the inlining of the check_card_num() method,
replicating the code. I would prefer an approach that avoids that.

I.e. one could make check_card_num() returning a bool that contains the
range check and is used within the asserts as easily.

However if the others do not object, I can live with it.

Thanks,
