The Non-Java structure editor allows SciFinder users experiencing problems with Java to draw structures for substance and reaction searches. The available features are equivalent to those in the Java version. Additional features will be released on an ongoing basis.
2. Java-based CAS Structure Editor
- Having trouble using the Java-based CAS Structure Editor since the release of Java 1.7.0_51? Try the non-Java editor or see our recommended solution (1/16/14)
- Using the Java based structure editor requires a Java Runtime Environment (JRE) and the associated Java plug-in to link the JRE to browsers. A 64-bit version of Java is required for 64-bit browsers.

- Newer browsers may require the most recent versions of Java for security purposes.
- Visit Javatester.org or the Oracle Java site to see if Java is installed and working on your computer.
- Information about downloading and installing Java is available at the www.java.com download page.
| ||* When using Java version 1.7.0_45 or later you may be required to "Allow" Java to run for each new SciFinder session. Look for the warning icon and when prompted select "Allow" or "Don't Block". |
Use the Non-Java structure editor if you have difficulties accessing or using the Java-based editor. For assistance contact the CAS Customer Center.
3. Standalone CAS Structure Editor
Users experiencing problems with the Java-based structure editor also have the option to download a standalone structure editor that can be used in conjunction with SciFinder.
Note: With minor exceptions, the standalone version has the same features as the Java-based version.
