WebRDKit uses an atom-based pi-electron counting algorithm to check aromaticity based on Huckel’s Rule. Therefore, this method identifies “true” aromaticity, rather than simply the RMG bond type. The method currently restricts aromaticity to six-membered carbon-only rings. This is a limitation imposed by RMG, and not by RDKit.
