-- Paul was bang on with the MARC codes for the classification numbers.

If you are using MARC21, you will probably also want to take note of the thesaurus you are using (I am assuming if you're using AMS you are not using LCSH), so in your subject tags (6xx), you'll add another $2msc
 
BTW, Library of Congress lists --

msc  Mathematical subject classification (Providence, RI: American Mathematical Society)

-- in its notes for FIELD 084 under Part III, Classification Sources,
                                                             (URL <http://www.loc.gov/marc/relators/relaclas.html>)
of its MARC Code Lists for Relators, Sources, Description Conventions (URL <http://www.loc.gov/marc/relators/relahome.html>), so Paul was right on that account as well!

In practice, Zeno, your library may choose to omit the $2 subfield in 6xx fields (CISTI in Canada does) but it's more friendly and better cataloguing practice to include an identifier for the subject heading/thesaurus used.

Hope this little addendum to Paul's answer helps.
