MARCEdit http://people.oregonstate.edu/~reeset/marcedit/html/downloads.html
has validation tools
&
the xcmetadataservicestoolkit (has/will have)
http://code.google.com/p/xcmetadataservicestoolkit/
in each you will have to specify what exactly you wish to validate/match
(Dublin Core scheme, MARC21 fields¹ contents, repeatability, etc.)
