The chemical compound "(1R)-O2,O3-isopropylidene-1-thiazol-5-yl-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, with the D-1,4-anhydro form indicating the absence of a hydroxyl group at the 1 and 4 positions, forming a carbon-carbon bond instead. The molecule is further modified with an isopropylidene group at the O2 and O3 positions, which protects the hydroxyl groups and contributes to the molecule's stability. A 1-thiazol-5-yl group is attached at the O5 position, providing a sulfur-containing heterocycle that can influence the compound's reactivity and properties. The trityl group, a bulky aryl group, is also present at the O5 position, which can affect the molecule's steric properties and interactions with other molecules. (1R)-O2,O3-isopropylidene-1-thiazol-5-yl-O5-trityl-D-1,4-anhydro-ribitol is likely used in advanced chemical research or as a building block in the synthesis of more complex molecules, given its intricate structure and functional groups.
The CAS Registry Mumber 71519-57-8 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 7 respectively. Calculate Digit Verification of CAS Registry Number 71519-57: (7*7)+(6*1)+(5*5)+(4*1)+(3*9)+(2*5)+(1*7)=128 128 % 10 = 8 So 71519-57-8 is a valid CAS Registry Number.
