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.
