The chemical compound "(1S)-O5-benzoyl-1-(7-benzoylamino-2-isopropyl-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 a 1,4-anhydro bridge, indicating the absence of hydroxyl groups at the 1 and 4 positions. The ribitol is modified with a 5-benzoyl group, which is a benzoyl moiety attached to the oxygen at the 5 position. Additionally, it has a pyrazolo[4,3-d]pyrimidin-3-yl group attached to the 1 position, which itself is substituted with a 7-benzoylamino and a 2-isopropyl group. The entire molecule is chiral, with the "1S" designation indicating the specific configuration of the molecule at the chiral center. (1S)-O5-benzoyl-1-(7-benzoylamino-2-isopropyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl)-D-1,4-anhydro-ribitol is likely to be of interest in medicinal chemistry due to its potential biological activity, possibly as a precursor or intermediate in the synthesis of pharmaceuticals.
The CAS Registry Mumber 67187-27-3 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 7 respectively. Calculate Digit Verification of CAS Registry Number 67187-27: (7*6)+(6*7)+(5*1)+(4*8)+(3*7)+(2*2)+(1*7)=153 153 % 10 = 3 So 67187-27-3 is a valid CAS Registry Number.
