The chemical "methyl-[O2-acetyl-O4,O6-((R)-benzylidene)-O3-(toluene-4-sulfonyl)-α-D-glucopyranoside]" is a complex organic compound derived from a modified sugar molecule, specifically an α-D-glucopyranoside. It features several functional groups, including an acetyl group at the O2 position, a benzylidene group at the O4 and O6 positions, and a toluene-4-sulfonyl group at the O3 position. The benzylidene group is in the R configuration, indicating its stereochemistry. methyl-[O2-acetyl-O4,O6-((R)-benzylidene)-O3-(toluene-4-sulfonyl)-α-D-glucopyranoside] is a derivative of a glucopyranoside, which is a monosaccharide in a pyranose form, and the presence of these various functional groups significantly alters its chemical properties and potential applications in fields such as pharmaceuticals, chemistry, and materials science.
The CAS Registry Mumber 2872-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,7 and 2 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2872-57: (6*2)+(5*8)+(4*7)+(3*2)+(2*5)+(1*7)=103 103 % 10 = 3 So 2872-57-3 is a valid CAS Registry Number.
