Once you are logged in, follow the steps below for your desired search type.

To search for Substances:
1. Select Substances on the search options menu above the main search query bar.
2.	Using the main search bar, input substance names, CAS Registry Numbers®, and/or document identifiers(such as patent number or DOI).
3. Press “Enter” or click the magnifying glass to submit your query.

4.	If you prefer to search for a substance by chemical structure:a. Click the Draw button on the right side of the main search bar.
b. Create your desired structure using CAS Draw.
c. Click the OK button to close the CAS Draw window and return to the home page.

	d. Y our structure now appears in the search bar. If further modifications to the search are needed,
text can be combined with structure searches.
e. Click the magnifying glass to submit your query.

5.	When your search is submitted, relevant results are displayed. You can further refine your results with:a. Structure Match – Use the selection tool on the left to define the desired structure match(for structure queries).
b. Filter – Select from a variety of filters found on the left-hand menu.
c. Sort – Rearrange your results based on relevance, molecular weight, and more using
the drop-down found above them.
