Vlookup Bands

I am trying to do a vlookup. I have attached an example of what I am trying to accomplish.

Basically, I have a range of number like this:

0-9 1
10-19 2
20-29 3
30-39 4
40-49 5

Instead of doing the vlookup up in one long column. I want to simply have it look up in the range of 0-9, etc and return the value.

Hope this makes sense.

Thanks for any help.
