If you'd used Word's Insert Caption tool, for which one of the captioning options is 'Equation', generating a list like the list of figures would be a trivial undertaking - you could actually produce a 'table' of equations using References>Insert Table of Figures, setting the Caption label to 'Equation'. Without that, you'd need a macro to go through all the fields looking for the SEQ field code pertaining to your numbering.
