The chemical compound "(1S)-O5-benzoyl-1-(7-dibenzoylamino-2-isopropyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl)-O2,O3-isopropylidene-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 molecule is further modified with an isopropylidene group at the O2 and O3 positions, which introduces a methyl group to each hydroxyl group, forming a cyclic structure. The 7-dibenzoylamino-2-isopropyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl group is attached to the ribitol through an O5-benzoyl linkage, adding a benzoyl group to the oxygen at position 5. This group itself contains a pyrazolo[4,3-d]pyrimidine ring, which is fused with a dibenzoylated amino group and an isopropyl substituent. The entire structure is chiral, with the 1S configuration indicating the specific arrangement of atoms around the chiral center. (1S)-O5-benzoyl-1-(7-dibenzoylamino-2-isopropyl-2H-pyrazolo[4,3-d]pyrimidin-3-yl)-O2,O3-isopropylidene-D-1,4-anhydro-ribitol is likely to have specific biological or pharmaceutical properties due to its intricate structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 67187-26-2 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 67187-26:
(7*6)+(6*7)+(5*1)+(4*8)+(3*7)+(2*2)+(1*6)=152
152 % 10 = 2
So 67187-26-2 is a valid CAS Registry Number.
