CAS Inventory Expert Services

The CAS Inventory Expert Service (IES) helps you obtain CA Index Names and CAS Registry Numbers® in order to complete your EPA TSCA PMN application under the Revisions of Premanufacture Notification Regulations: Final Rule.

CAS Inventory Expert Services request

A CA Index Name is the standard output for substances submitted to the CAS Inventory Expert Service. If your substance has an existing CAS Registry Number®, it will also be provided to you. If you would like to have a new CAS Registry Number assigned to your substance, and/or require the "Super Rush" service, please check the appropriate box(es).

Note: If you request assignment of a new CAS Registry number for a substance not already present in the CAS Registry system, that assignment will make your substance publicly available in CAS Registry®. Customer identity information will be kept confidential. If you wish to maintain confidentiality for your Substance's identity, you should request only a CA Index Name or retrieval of an existing CAS Registry number.
