COMMENTS
1/a(n) must contain also at least one nonzero digit after n if n ends with 0; e.g., a(10)=19 because 19 is the smallest integer whose reciprocal (0.052631578947368421052...) contains the digits "10" followed by at least one nonzero digit (to avoid 1/10 = 0.1000...).
EXAMPLE
11 is the smallest integer whose reciprocal (0.0909...) contains 9, hence a(9) = 11.
