You dont need regex. Use str.StartsWith("IS1").

Not clear from the question, so here are a few options.

You want to find out if ANY string in the list starts with IS1

var found = values.Any(item => item.StartsWith("IS1"));

You want to find all the strings in the list which start with IS1

var matches = values.Where(item => item.StartsWith("IS1"));
