(ARIN did a reconciliation in July 2009 of all ASNs marked as “assigned by ARIN” with our own internal records to find out whether any holes existed, and began assigning such ASNs in August 2009, including AS numbers in the range 1708 thru 1726).

       I searched for any historical registrations from this block
in the RADB and found a number of routes with an origin
of AS1717.   They date from 1995 and were registered for the
Université Pierre et Marie Curie by Renater.  They have long
since been removed from the RADB.
Here's an example --

descr: Universite Pierre et Marie Curie

origin: AS1717
