1 Chemical Abstracts Service
					 (CAS) registry numbers are unique numbers assigned to a chemical substance. The
					 CAS registry numbers were published by the U.S. Environmental Protection Agency
					 in 40 CFR Part 264 , Appendix IV
2 Common synonyms include those
					 widely used in government regulations, scientific publications, commerce and
					 the general public. A trade name, also known as the proprietary name, is the
					 specific, registered name given by a manufacturer to a product. Trade names are
					 listed in
italics
. Common synonyms and trade names should be
					 cross-referenced with CAS registry number to ensure the correct substance is
					 identified.
3 This is a combined chemical
					 substance which includes cis 1,3-Dichloropropene (CAS RN 10061-01-5) and trans
					 1,3-Dichloropropene (CAS RN 10061-02-6).
4 Polychlorinated biphenyls (CAS
					 RN 1336-36-3); this category contains congener chemicals (same molecular
					 composition, different molecular structure and formula), including constituents
					 of Aroclor-1016 (CAS RN12674-11-2), Aroclor-1221 (CAS RN 11104-28-2),
					 Aroclor-1232 (CAS RN 11141-16-5), Aroclor-1242 (CAS RN 53469-21-9),
					 Aroclor-1248 (CAS RN 12672-29-6), Aroclor-1254 (CAS RN 11097-69-1), and
					 Aroclor-1260 (CAS RN 11096-82-5).
5 Xylene (CAS RN 1330-20-7)
					 refers to a mixture of three isomers, meta-xylene (CAS RN 108-38-3),
					 ortho-xylene (CAS RN 95-47-6), and para-xylene (CAS RN
					 106-42-3)
