ChemDraw Beta 21.0 Portal
Just thought I'd mention that the folder to store applescripts is username:Library:Application Support:com.perkinelmer.ChemDraw:Scripts. The User Library folder is hidden by default but can be viewed from the Finder of Mac OS, pull down the “Go” menu and hold down the SHIFT key and you can choose “Library” from the drop down list. You can drag this into the side bar for easy access.
I think right-cliking on the ChemDra application in the Dock should propose something like showing the scripts folder
Also the link on "http://www.cambridgesoft.com/services/documentation/sdk/chemdraw/AppleScript/index.htm" Macintoshs in Chemistry should be https://www.macinchem.org. :-)
