finding the 3rd to 5th texts in a series of texts

I'm trying to figure out a function that allows me to give a description when the three specific numbers are shown in a series of text.

In my attached spreadsheet, I have 345 for cash and 567 for credit. On cell A3, I have 12345-01. So, using the given on cells A6:B7, the result for B3 is Cash.

Thanks

Put the following formula in cell B3 and confirm it with ctrl+shift+enter:
=INDEX($B$6:$B$7,MATCH(1,FIND($A$6:$A$7,A3)^0,0))

If you need this formula to NOT be case-sensitive, then replace "FIND" with "SEARCH".
