%N a(n) is the smallest pandigital number divisible by n, or 0 if no such pandigital number exists.

%C Note: in this sequence, "pandigital" numbers are defined as in A050278 (i.e., with each of the ten digits 0..9 appearing exactly once).

%C The first 99 terms coincide with those of A061604. - _Giovanni Resta_, May 15 2018

%C From _Jon E. Schoenfield_, May 19 2018: (Start)

%C Record high values exceeding 2*10^9 begin a(10001) = 2650134987, a(20002) = 2750134986, a(27775) = 3012948675, a(40004) = 3760215984, a(44440) = 4123987560, a(50005) = 6820431975, ...

%C a(n)=0 for every n divisible by 100. Other than multiples of 100, the smallest values of n for which a(n)=0 are 37037 and 55550. The last nonzero term is a(9876543210) = 9876543210. (End)

%e a(11) = 1024375869 = 11 * 93125079 because it is the smallest pandigital number that is divisible by 11;

%e a(100) = 0 because there is no pandigital number that is divisible by 100.
