The question is incomplete:

Do you require that the header is EXACTLY like the one you posted? In this case, there is nothing CSV-specific in your question. Instead, the problem boils down to finding out, whether the first line of a file has a certain content.

Or do you require that the header is STRUCTURALLY like the one you posted? For example, the CSV-file format allows fields to be quoted; or, you might consider trailing spaces after the header names insignificant; or you might allow the fields to occur in any order. In this case, you need to specify, what exactly are the conditions to regard the header valid.
