List Numbers
ECHA also applies the EC number format to what it calls "List numbers". The number are assigned by when a substance is pre-registered or inquired about under the REACH Regulation. They are not official because they have not been published in the Official Journal of the European Union. The number of these two categories is open ended, as substances are continually being added.
Scope | Format |
---|---|
Automatically assigned, e.g. to pre-registrations of substances with a CAS No. | 6xx-xxx-x |
Assigned to substances after inquiries by the ECHA Substance ID Team | 7xx-xxx-x |
Automatically assigned, e.g. to pre-registrations without a CAS No. or other numerical identifier (including reaction masses of more than one substance) | 9xx-xxx-x |
