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?

I can provide the docs. But only if you are really really 100% sure you actually want the job.

Eveidnce [sic] != proof.2^5-1 (=31) is prime. 2^31-1 is prime. But 2^(2^31-1)-1 is composite, factors are known.

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.
