This work presents STOUT V2.0, an improved successor for SMILES to IUPAC name Translator. This work represents a significant advancement in automated deep learning-based IUPAC name generation. It was, however, only possible due to the availability of IUPAC names generated by deterministic naming algorithms, in our case, by OpenEye's Lexichem software. A substantial improvement was achieved by leveraging the transformer-based models for deep learning.
