SciFinder News

April Update

The non-Java structure editor has been further enhanced, and it is now the default editor unless the Java version is selected. The latest improvements (which are already present in the old Java version) include:
  • Variable Attachment Point Tool: specify multiple positions on a ring system where a substituent can attach to broaden your search scope
  • Functional Groups Tool: create a reaction query where a reactant, reagent, or product is represented by a functional group to cast a wider net
  • Text node entry: Use text entry to specify atoms at node points.
See What's New for more information.

New "Need to Know" Training Videos

CAS has added some short videos on its Training page that cover basic techniques that users need to know to use the tool effectively. A good way for beginners to get a feel for SciFinder!

bug Bug Report:
Java Structure Applet

SciFinder's Java structure drawing applet continues to be affected by routine updates to Java, operating systems (mainly Mac OS), and web browsers. For tips see our FAQ page. CAS has provided details about the Java 7 Update 51 settings. However, you should now be using the non-Java editor unless there is some functionality still available only in the Java version that you absolutely have to have. The non-Java editor is rapidly converging with the Java one.
