Search the industrial chemicals inventory
The Australian Inventory of Industrial Chemicals (Inventory) is a database of more than 40,000 chemicals available for industrial use in Australia. For information about the safety, hazard and risks associated with chemicals, use our assessment search.
Search by CAS number
This is the best method. A CAS number contains digits that are divided by hyphens into 3 parts.
The CAS Registry is maintained by CAS and they also assign CAS numbers to chemicals (for a fee). They have a limited free online resource called Common Chemistry for searching CAS numbers.
Other ways to try and find your CAS number include:
- looking at Safety Data Sheets — you'll need to contact the manufacturer or supplier
- through an internet search
- search online catalogues of chemical suppliers

Searching by keyword
CAS proper name
If you do not have the CAS number your next best option is to search using the CAS name for the chemical.
Common names
Some common names for chemicals are on the Inventory but are restricted to the most commonly used chemicals. Your results will most likely be a very broad list of candidate chemicals.
Molecular formula
You can search by molecular formula e.g. C12H12N2O3, but you may get a very large number of results. Be as specific as possible in your search to get the most meaningful results.

- European Chemicals Agency (information about chemicals in Europe)
- United States Environment Protection Agency Aggregated Computational Toxicology Resource
ACToR (Aggregated Computational Toxicology resource) is EPA's online warehouse of all publicly available chemical toxicity data and can be used to find all publicly available data about potential chemical risks to human health and the environment. - CosIng Database search page
This European Commission searchable database has information on cosmetic ingredients. It contains CAS RNs and International Nomenclature Cosmetic Ingredient (INCI) names and numbers. - National Library of Medicine
This United States' site lists chemicals and available toxicity information. It is useful for listing chemicals that are not on major inventories. - National Institute of Standards and Technology Chemistry (NIST) WebBook
This website of the U.S. Department of Commerce provides access to data compiled and distributed by NIST under the Standard Reference Data Program. - Common Chemistry (from Chemical Abstracts Service)
