It is technically possible as long as your IP space from provider A is a /24
or greater, but it is highly unlikely that 2 different providers will allow
you to peer via a private AS number. It would be better to get your own
public AS number, it isn't too expensive and they will give it to you as
long as you are peering with at least 2 different providers.
Another thing to consider is where your /24 is allocated from, if it is not
from the traditional class C address space certain providers will not accept
a /24 announcement, that is rare but it does happen, Verio used to refuse to
accept /24 announcements that were not out of the traditional class C
address space, I am not sure if they still have that policy in place.

Subject: is it possible to use private AS# peering with 2 ISPs?
Dear all,
We are using ISP A's service. ISP A assigned ip range and private AS number
to us. For the backup purpose, we are going to use ISP B as well. We are
going to keep our IP range and private AS # assigned by ISP A. Is it
possible for us to use this private AS# to peer with ISP B?
Please advise. Thanks.
