When creating an experiment in the ELN containing a Stoichiometry data type with a chemistry canvas data type AND if you have access to a registration group containing a chemistry canvas field a new option will display in the ELN. This register option allows you to register a structure directly from your stoichiometry grid.

Once prompted choose the entity under which you would like to register the molecule.

The system will prepopulate the structure from the stoichiometry row you register. If configured correctly a link to the ELN you are currently registering from will be inserted automatically into the new reg record as well The registration ID will also be inserted into the table
