Restore from scratches (Posted on 2013-10-08) Difficulty: 2 of 5
I have multiplied all odd integers below 15.

The penultimate digit of the 6-digit resulting number is 3.

The above hint is sufficient for restoring the correct result without reverting to my multiplication.

Go ahead, replace the asterisks by digits: N=****3* !
