Example for the PubChem identifiers exchange services -
PubChem services
In case of batch retrieval, browse for the .csv file containing list if compound names.
I found it easier than PUG REST API as it does not ask for replacing white-space or parentheses with appropriate notations like %20, %28 or %29.
Both services performs equally well as I passed-on the unresolved compound names to both of them (after placing notations for white-space, parentheses to PUG REST API) generated results are similar.
For example -
C4995 iso-borneol
