RP to Group Mapping

If I want to configure RP to Group mapping in such a fashion that

R3 should be a mapping agent for all multicast group for R1 with even number
first octet, and
R3 should be a mapping agent for all multicast group for R2 with odd number
second octed.

The easiest way I could do is

access-list 1 permit 0.0.0.0 254.255.255.255 for R1
access-list 2 permit 1.0.0.0 254.255.255.255 for R2

but I want to be more granular then I can configure such as

access-list 1 permit 224.0.0.0 7.255.255.255 for R1
access-list 2 permit 225.0.0.0 7.255.255255 for R2

Can someone confirm if the 2nd option will work. I worked out in binary it
looked fine.

Regards,

Ahmed
