From 1-10, only one,two,four,five,six,eight and ten fits the criteria and the 'teens' are cancelled out.

From twenty to thirty nine, all are out and forty,forty one and forty six fits. Sixty,sixty one and sixty four are the only ones fitting then on with eighty and eighty four as the last numbers before hundred to fit in.
