The chemical compound "(1R)-1-(2-benzyl-thiazol-5-yl)-O2,O3-isopropylidene-O5-trityl-D-1,4-anhydro-ribitol" is a complex organic molecule with a unique structure. It features a ribitol core, which is a sugar alcohol derivative, with a 1,4-anhydro ring, indicating the absence of a hydroxyl group at the 1 and 4 positions, forming a carbon-carbon bond instead. The molecule is chiral, with the "1R" configuration indicating the specific three-dimensional arrangement of atoms around the chiral center. It has a 2-benzyl-thiazol-5-yl group attached to the ribitol, which contributes to its chemical properties. The "O2,O3-isopropylidene" part of the name suggests that the hydroxyl groups at the 2 and 3 positions are protected by an isopropylidene group, which is a common protecting group in organic synthesis. Additionally, the "O5-trityl" indicates that the hydroxyl group at the 5 position is protected by a trityl group, which is a bulky, electron-rich protecting group. (1R)-1-(2-benzyl-thiazol-5-yl)-O2,O3-isopropylidene-O5-trityl-D-1,4-anhydro-ribitol is likely used in advanced organic synthesis, particularly in the preparation of complex molecules where protecting groups are crucial for selective reactions.
The CAS Registry Mumber 71519-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 71519-56: (7*7)+(6*1)+(5*5)+(4*1)+(3*9)+(2*5)+(1*6)=127 127 % 10 = 7 So 71519-56-7 is a valid CAS Registry Number.
