The factual accuracy of this chemistry-related file is disputed.
The dispute is about: cannabichromenic acid should have the carboxylic group at C6, not C8 (benzopyrane/chromene numbering), according to the scientific literature and papers, i.e. the cyclization should occur at the other -OH group. Reference: doi:10.1016/S0031-9422(98)00278-7.
