Maxscript - Quickest method to check formesh changes

What would be the quickest method, other than running through each vertex position, to check if a mesh has been modified?
I`m currently recording changes to the bounding box, but this won’t catch and mesh changes that don’t effect this.

I`m basically looking to generate a hashcode for each mesh to check if it has been modified and the geometry changes is a bit of a bottleneck at the moment.

cheers!
Andy
