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.

WebInChI Keys are generated using algorithms that take into account the structure of the chemical compound, including its atoms, bonds, and other structural features. The InChI Key is intended to be a unique identifier for a chemical compound, meaning that no two chemical compounds should have the same InChI Key.
