Export as mol file
A number of publishers are seeking to add extra value to publications by including access to chemical structure information to aid searching and indexing. More details are included in this comment from Elsevier.
Elsevier would like to enrich online articles by visualising and providing details of chemical structures you define as the main chemical compounds described in your article. For this purpose, mol files of the key compounds can be uploaded in EES. Please use your preferred drawing tool to export chemical structures as mol files and ensure that they are well defined and do not contain aromtic bonds, R-Groups or other variables. Submitted mol files will be available for downloading from your online article on ScienceDirect. Furthermore, Elsevier will generate InChI keys from the mol files and include them in the online article, which increase the online searchability of your article e.g. in Google. InChI keys will also be used to link the article to additional data in Reaxys.
Since you need to export each structure as an individual file this will become somewhat tedious, fortunately Brian Myers has written an applescript that greatly helps the process for ChemBioDraw users
