1,3-Anhydro-2,4,6-tri-O-(p-bromobenzyl)-β-D-glucopyranose is a complex organic compound derived from β-D-glucopyranose, a monosaccharide. This chemical features a glucose molecule with three hydroxyl groups at the 2, 4, and 6 positions, each substituted with a p-bromobenzyl group. The 1,3-anhydro structure indicates the absence of hydroxyl groups at these positions, with a double bond formed between carbons 1 and 3. 1,3-anhydro-2,4,6-tri-O-(p-bromobenzyl)-β-D-glucopyranose is significant in organic synthesis and carbohydrate chemistry, often used as a building block for the synthesis of more complex molecules and as a protecting group in the preparation of various glycoconjugates. Its unique structure with bromine-substituted benzyl groups also makes it a valuable intermediate in the synthesis of pharmaceuticals and other bioactive compounds.
The CAS Registry Mumber 89243-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 89243-40: (7*8)+(6*9)+(5*2)+(4*4)+(3*3)+(2*4)+(1*0)=153 153 % 10 = 3 So 89243-40-3 is a valid CAS Registry Number.
