WebThe InChI software as you might be thinking about is a reference implementation of the description laid out in the paper. The specification is not the code, but the algorithm that has been implemented by code. You absolutely do not need a molfile to create an InChI string, if you understood the algorithm, you can do it by hand. WebFeb 9, 2024 · Improvements in InChI treatment of stereoconfiguration.
