Enter the substance name or CAS Registry Number to identify the substance. The query must match the substance identifier exactly. CAS SciFinder will not match a partial name or number.

Notes:

  • You may enter multiple CAS RNs separated by a space, no commas or other punctuation. The search field has a 2000-character limit.
  • You may search using Greek letters and their equivalents.

As you enter the text, autosuggestions may appear. You can select from the list of suggestions, or continue typing. Click the magnifying glass or press Enter to submit the query.
