so I added an "if ((n-floor (n / 100) * 100) == 63" , to find only the numbers that end with 63.

You could have done n%100==63 instead.
Anyway thanks.
With the counterexample [62611454518799, 9] I need to go back to the drawing board.
I had a PM for Dr. Sardonicus, wherein he describes a method to generate counterexamples for a=4. Perhaps he will post his method here.
