3,4,6-tri-O-acetyl-1,2-O-dimethoxyorthocarbonyl-α-D-glucopyranose is a complex organic compound derived from α-D-glucopyranose, a monosaccharide. This chemical is characterized by the presence of three acetyl groups attached to the 3rd, 4th, and 6th hydroxyl groups, and a dimethoxyorthocarbonyl group bridging the 1st and 2nd hydroxyl groups. The acetyl groups serve to protect the hydroxyl groups, while the dimethoxyorthocarbonyl group acts as a protecting group for the glycosidic bond, preventing unwanted reactions at the anomeric center. 3,4,6-tri-O-acetyl-1,2-O-dimethoxyorthocarbonyl-α-D-glucopyranose is often used in the synthesis of complex carbohydrates and glycoconjugates, where precise control over the protecting groups is crucial for achieving the desired product. Its structure allows for selective deprotection and functionalization, making it a valuable intermediate in carbohydrate chemistry.

4768-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4768-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4768-78:
(6*4)+(5*7)+(4*6)+(3*8)+(2*7)+(1*8)=129
129 % 10 = 9
So 4768-78-9 is a valid CAS Registry Number.
