2,3,6-tri-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-β-D-glucopyranosyl fluoride is a complex organic compound that belongs to the class of glycosides. It is a derivative of β-D-glucopyranose, a monosaccharide, with multiple acetyl groups attached to its hydroxyl groups. The compound features a β-D-glucopyranosyl fluoride moiety at the 4-position, which is further glycosylated with a tetra-O-acetyl-β-D-glucopyranosyl group. The acetyl groups protect the hydroxyl groups, which is crucial for preventing unwanted side reactions during chemical synthesis. 2,3,6-tri-O-acetyl-4-O-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-β-D-glucopyranosyl fluoride is significant in the field of carbohydrate chemistry, as it serves as a building block for the synthesis of more complex oligosaccharides and glycoconjugates, which are essential components of many biological molecules and have applications in医药, 生物学研究, and material science.
The CAS Registry Mumber 440-03-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 0 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 440-03: (5*4)+(4*4)+(3*0)+(2*0)+(1*3)=39 39 % 10 = 9 So 440-03-9 is a valid CAS Registry Number.
