The chemical compound "(1S)-O5-benzoyl-1-(7-benzoylamino-2-methyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl)-D-1,4-anhydro-ribitol" is a complex organic molecule with a unique structure. It features a ribitol core, which is a sugar alcohol, with an anhydro bridge between the 1 and 4 positions, indicating the absence of a hydroxyl group at these positions. The ribitol is further modified by a 1S configuration, indicating the chirality of the molecule. Attached to this core is a pyrazolo[4,3-d]pyrimidin-3-yl group, which is a heterocyclic ring system with a benzoylamino substituent at the 7-position, and a methyl group at the 2-position. This pyrimidinyl group is further connected to a benzoyl group at the O5 position, adding to the complexity of the molecule. The entire structure is a derivative of ribitol, with multiple functional groups and substitutions that contribute to its specific properties and potential applications in fields such as pharmaceuticals or chemical research.
The CAS Registry Mumber 67187-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,8 and 7 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 67187-23: (7*6)+(6*7)+(5*1)+(4*8)+(3*7)+(2*2)+(1*3)=149 149 % 10 = 9 So 67187-23-9 is a valid CAS Registry Number.
