By now you must have revalidated your FI(A) rating under JAR/FCL requirements, including completion of the 'declaration of knowledge' form.
As a CRE you are entitled to conduct Class Rating renewals/revalidations within your CRE authorisation.
So, in my opinion, if your licence is current, your own SEP Class rating and FI(A) rating are valid and your CRE authorisation is valid and includes SEP examining approval, I would say that you are appropriately qualified.
Your CRE 'number' is probably what the Swiss mean by a 'JAR/FCL number'.
