The problem with AS numbers is the aggregation. What works for one individual is a reflection of their connection to the network.
For example, within the State of XYZ University system, there are multiple AS#s, one per campus, reflecting traffic flow through the state-wide network. But the State provides a consolidated network inter-connection for all campuses and universities to the rest of the world. So outsiders see the aggregated network AS# only.
There are organizations that make AS lookups available, but again, it reflects their position in the network. The best know is Cymru: http://www.team-cymru.org/Services/ip-to-asn.html
