Ray Chandler, Table of n, a(n) for n = 1..10000

EXAMPLE

No power of 2 ends with 3, so the first term is 2.

No power of 2 is == 22 (mod 100), since 4 does not divide 22, so the next term is 3 (and 4 does divide 32).

No power of 2 is == 332 (mod 1000), since 8 does not divide 332, so the next term is 2 (and 8 does divide 232). And so on.
