Because if we take, for example, a=10, n=4 and i=3, we have :

s(10^(4*3)) = s(10^12) = 1499694822171
10^3+1 = 1001

And 1001 do not divide 1499694822171.
I was just tossing out a couple things that seemed of interest. I can't do more for a few days. If it's not valid, that's fine. I'll look at it more in a few days.
