Formula for finding part of a word in a cell

Hello,

I was wondering if there is a formula for finding part of a word in a excel cell. For example I have several manufacturers name in one cell and some manufacturers name in another cell. I want it to tell me if they are the same. For example in cell A1 I have ABC and in cell H1 I have ABC Corp. Can it tell me that they are the same because of the ABC?

Thanks
