%e a(2) = 11 which is prime. Also, 11 = 10 + 1, which is n + product of nonzero digit of n.

%e a(9) = 89 which is prime. Also, 89 = 81 + (8*1), which is n + product of nonzero digits of n.

%e a(10) = 107 which is prime. Also, 107 = 83 + (8*3), which is n + product of nonzero digits of n.

%t Select[Table[n + Times @@ DeleteCases[IntegerDigits[n], 0], {n, 1000}], PrimeQ]
