α-D-Altropyranose is a monosaccharide, specifically a hexose sugar, derived from altrose, which is an aldohexose found in nature. It is a cyclic form of altrose, where the molecule has undergone an intramolecular reaction to form a pyran ring structure. This ring structure consists of five carbon atoms and one oxygen atom, with the hydroxyl groups (-OH) attached to each carbon in specific positions. In α-D-altrofuranoside, the anomeric carbon (the first carbon in the ring) has an α-configuration, meaning the hydroxyl group on this carbon is on the opposite side of the ring compared to the hydroxyl group on the fifth carbon. This specific arrangement is crucial for the molecule's stereochemistry and its interactions with other molecules in biological systems. α-D-Altropyranose plays a role in various biochemical processes and can be found in some polysaccharides and glycoconjugates, contributing to the structural diversity of carbohydrates in living organisms.
The CAS Registry Mumber 7282-80-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,8 and 2 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7282-80: (6*7)+(5*2)+(4*8)+(3*2)+(2*8)+(1*0)=106 106 % 10 = 6 So 7282-80-6 is a valid CAS Registry Number.
