how to get the IUPAC names from a list of names

hi,

i am working with a big dataset of molecules containing the compounds names. Using the proper nodes, KNIME was able to give me the SMILES strings of only 2700 compounds out of 9500 and that’s because for a huge block of compounds the IUPAC name wasn’t reported on the list.

how can I get the IUPAC names from a list of compounds names?

thank you so much in advance!
