%N Numbers whose carryless sum of divisors is zero.
%C Equivalently, numbers k such that A323394(k) = 0.

%e For k = 87:
%e - the divisors of 87 are: 1, 3, 29, 87,
%e - the sum of units is: 1 + 3 + 9 + 7 = 20 == 0 (mod 10),
%e - the sum of tens is: 2 + 8 = 10 == 0 (mod 10),
%e - hence A323394(87) = 0 and 87 belongs to the sequence.
