Yes!  Dead easy.

Use an external script, written in your favourite language, to look up the 
number in some sort of database and return failure  (exit 1)  if it finds it 
there, or success  (exit 0)  if not.  Call this with System() in dialplan.  If 
the System() call succeeds  (meaning the number was not found in the 
database),  Asterisk will move onto the next priority; if it fails  (meaning 
the number was in the database)  then it will move on by an extra 100.

Alternatively, you can read the value of ${SYSTEMSTATUS} to get the exit code.
