If a compound is not listed in a directory under a certain CAS number this does not necessary indicate that this compound cannot be commercially used in a country. It is possible that this compound might fall under a different category or is exempt from listing requirements. Some salts for example are considered in some countries regulations not new compounds and if the acid and the amine is listed the salt is also listed. Consult your supplier for information.
