SCHEDULE

Scheduled Toxic Chemicals and Precursors

		(CAS registry number)
Notes: 1. This Schedule sets out Schedule 1 to the annex on chemicals to the Convention as corrected. 2. In this Schedule the reference to the CAS registry is to the chemical abstract service registry. 3. This Schedule must be read subject to the following proposition, which is based on a note in the Convention: where reference is made to groups of dialkylated chemicals, followed by a list of alkyl groups in parentheses, all chemicals possible by all possible combinations of alkyl groups listed in the parentheses must be taken to be listed in the Schedule.
