%N Odd numbers whose set of prime factors (taken with multiplicity) uses each digit from 0 to 9 exactly once.
%C This sequence also contains numbers not ending in 5 (i.e., 78369189).
%C a(1916) = 240510701 is the first semiprime with this property.
%C No pandigital number is in the sequence.

%e 42279945 = 3*5*1049*2687 is in the sequence since the set {3, 5, 1049, 2687} can be formed from the digits 0 to 9 and each digit is used only once.
