With ~2^265 atoms in the observable universe, that means we only have to store 2^108999735 coefficients into each atom. So, IOW, not a problem at all, why haven't we done it yet?

And the digit sum of 10 is 1.

BTW: Repeated digit sum is just another way of computing the remainder when divided by 9.

The OP is wasting time trying to use it.
