COMMENTS

A005349(k) belongs to this sequence iff A113315(k) is not a multiple of 10.

This sequence is infinite as it contains A133384 and A199682.

Each Niven number can be uniquely written as a(m)*10^z for some m > 0 and z >= 0.

This sequence contains numbers with k trailing zeros for any k >= 0; for example R(2^k) * 10^k (where R = A002275).
