The first 33 terms are regular, as in A008592.
The multiples of 1 is A064413 itself. The multiples of 2 is A064469. The multiples of 3 are 3*A155963(n).
The first 15 multiples of 4 are 4*A115510, but then become different. The multiples of 5 are A158486,
also represented by A158504. The first 85 multiples of 6 coincide with A008588(1..85), then deviate.
The first 56 multiples of 9 are A008591(1..56), and then deviate. Multiples of 13 are in A158605.
