from `man rhn_register`:

FILES
        /etc/sysconfig/rhn/systemid
               The  digital  server  ID for this machine if the system 
has been registered onto Red Hat Network.  This
               file does not exist otherwise.

if that file exists on a system, it's a pretty good bet that at least 
once in the past it was successfully registered.

however, if the system was registered in the past and has now been 
deleted, checking for the systemid file will not help you.  you might 
try querying the RHN API; look at the system handler 
(https://rhn.redhat.com/rhn/apidoc/system/SystemHandler.jsp) and 
consider using the getDetails or getEntitlements calls.
