The 2023 edition of the Braille Code for Chemical Notation Using the Nemeth Code has been aligned with Unified English Braille (UEB) and reflects current developments in chemical notation. Professional chemistry faculty, braille transcribers, and representatives from the Committee on Nomenclature, Terminology, and Symbols of the American Chemical Society have been involved in this effort.
