Methyl 2-O-acetyl-β-D-mannopyranoside is a complex organic compound that belongs to the class of carbohydrates, specifically a derivative of the sugar mannose. It is characterized by a pyranose ring structure, which is a six-membered ring, and features an acetyl group attached to the second carbon atom (2-O-acetyl). This acetyl group is an ester derived from acetic acid, which adds a methyl and a carboxyl group to the sugar molecule. The compound is a methyl glycoside, meaning it has a methoxy group (-OCH3) at the anomeric carbon, which is the carbon involved in the glycosidic bond. Methyl 2-O-acetyl-β-D-mannopyranoside is often used in organic synthesis and as a building block in the preparation of more complex carbohydrates and glycoconjugates, playing a significant role in the study of carbohydrate chemistry and biochemistry.
The CAS Registry Mumber 2773-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,7 and 3 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2773-68: (6*2)+(5*7)+(4*7)+(3*3)+(2*6)+(1*8)=104 104 % 10 = 4 So 2773-68-4 is a valid CAS Registry Number.
