Well, for one thing, CAS (like DUNS) identifiers are proprietary.  They can't 
be reused for the purposes of identification in non-licensed systems.  That 
causes no end of trouble for researchers, government agencies and corporations 
who have bought into those proprietary identification schemes only to find out 
that they can't reuse the identifiers in new contexts.

An example is the US Environmental Protection Agency, who uses CAS numbers.  
They cannot reuse those identifiers when they publish open government data.  
They are not thrilled about that.  The EPA is now publishing their own 
identifiers.  How long will CAS last as a "standard"?  How many ids has the 
Encyclopedia of Life developed?  Or Wikipedia?

DUNS numbers, another widely used proprietary identification scheme, are very 
similar.  Orgpedia [1] and similar approaches are and have been started just to 
break the deadlock of that scheme.

Face it:  People just hate being boxed in.  Sure, you can make a business model 
out of doing so, but don't expect anyone to love you for it.  The Web allows 
people to think about not boxing themselves in.  That is a direct threat to 
those older and less friendly business models, DUNS and CAS included.

Regards,
Dave
