Cashier's check name mistake?

I sold my husband's car and the guy that bought it got a cashier's check. He put my WHOLE name on it but instead of putting Kasey, he put Casey. My name is with a "k" not a "c". I have a bill of sale that we both signed. I was thinking that I could just take in the bill of sale and the check but I don't know if they will cash it?? What do you think?
