How to check whether package body was defined correctly?

There is a package containing lot of procedures exists in the system. Whenever we use the procedures of this package, it gives some errors. Now, I would like to check whether there were compilation errors reported when this package body was created/defined earlier. Is it possible to do this check now i.e. after they were created earlier.
