recent discussion across these questionsI think the answer is 11. The digit sum is 2. Possible digit multisets: {2,0,0,...,0} and {1,1,0,...,0}. For the first, the 2 must be the first digit (since if it's not, the number would start with 0, which is not allowed for an 11-digit number). So 1 number. For the second, the first digit must be 1 (can't be 0), and the other 1 can be in any of the remaining 10 positions. So 10 numbers. Total 11. But is there any other combination? What about {1,0,1,0,...}? That's the same as two 1s. So 11.
