I am a 2 digit number. You can divide me by every single digit except for 5 and 7. Add my digits together and the sum is 9. What number am I?

It's an even number
Factors of 9:
0 + 9  No
1 + 8  No
2 + 7  ?
3 + 6  ?
4 + 5  No

Can't divide by 8 either, so I am stuck. This problem was on my actual homework today.
