2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl-(1->4)-2,3,6-tri-O-acetyl-α-D-glucopyranosyl fluoride is a complex organic compound consisting of two glucose molecules connected through a glycosidic bond. The first glucose molecule is α-D-glucopyranosyl, and it is connected to the second glucose molecule, which is also α-D-glucopyranosyl, through a 1->4 linkage. 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl-(1->4)-2,3,6-tri-O-acetyl-α-D-glucopyranosyl fluoride is characterized by the presence of acetyl groups (-COCH3) protecting the hydroxyl groups (-OH) of the glucose molecules, with the first glucose molecule having four acetyl groups and the second having three. The presence of a fluoride group (-F) at the end of the second glucose molecule makes 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl-(1->4)-2,3,6-tri-O-acetyl-α-D-glucopyranosyl fluoride a potential glycosyl donor in chemical synthesis, particularly in the preparation of complex oligosaccharides and glycoconjugates.
The CAS Registry Mumber 440-02-8 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 2 respectively. Calculate Digit Verification of CAS Registry Number 440-02: (5*4)+(4*4)+(3*0)+(2*0)+(1*2)=38 38 % 10 = 8 So 440-02-8 is a valid CAS Registry Number.
