The chemical compound "methyl-[O4,O6-((R)-benzylidene)-O2-(toluene-4-sulfonyl)-O3-trifluoroacetyl-α-D-glucopyranoside]" is a complex, modified sugar derivative. It features a methyl group attached to a glucopyranoside ring, which is a type of sugar molecule. The glucopyranoside ring has been modified with several functional groups: a benzylidene group at the 4th and 6th positions, a toluene-4-sulfonyl group at the 2nd position, and a trifluoroacetyl group at the 3rd position. The "R" in the benzylidene group indicates that the benzylidene is in the R configuration, which refers to the spatial arrangement of the molecule. methyl-[O4,O6-((R)-benzylidene)-O2-(toluene-4-sulfonyl)-O3-trifluoroacetyl-α-D-glucopyranoside] is likely used in advanced chemical research or as an intermediate in the synthesis of pharmaceuticals or other complex organic molecules, given its intricate structure and the presence of various protecting and functional groups.
The CAS Registry Mumber 633-51-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 3 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 633-51: (5*6)+(4*3)+(3*3)+(2*5)+(1*1)=62 62 % 10 = 2 So 633-51-2 is a valid CAS Registry Number.
