I am pretty sure that nothing with a zero as the second digit can be a hit.

Hello Math-Fun,
We write, after each digit D of K, the cumulative sum of the digits so far. When this is done, we concatenate the results and iterate the process.
If, at some stage, the concatenation starts with the string K, we have a hit.
K = 344567 Cumulative sums of K's digits: 3, 7, 11, 16, 22, 29
Concatenation and iteration: 3711162229 3, 10, 11, 12, 13, 19, 21, 23, 25, 34
Concatenation and iteration: 3101112131921232534 3, 4, 4, 5, 6, 7, 9,...
HIT!
Are all integers potential hits? Best É.
