3.6-Diacetamido-2.4.5-tri-O-acetyl-3.6-dideoxy-D-altrose-diethyldithioacetal is a complex organic compound with the molecular formula C20H31NO9S2. It is a derivative of D-altrose, a rare sugar found in nature, with modifications that include the removal of two hydroxyl groups (dideoxy), the addition of two acetamido groups at the 3 and 6 positions, and the acetylation of the hydroxyl groups at the 2, 4, and 5 positions. The molecule also features a diethyldithioacetal group, which is a protecting group used in organic synthesis to prevent oxidation of the sugar's carbonyl group. 3.6-Diacetamido-2.4.5-tri-O-acetyl-3.6-dideoxy-D-altrose-diethyldithioacetal is significant in the field of carbohydrate chemistry, where such derivatives are studied for their potential applications in pharmaceuticals, as chiral building blocks, or for understanding the reactivity and properties of sugars.
The CAS Registry Mumber 4157-10-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,5 and 7 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4157-10: (6*4)+(5*1)+(4*5)+(3*7)+(2*1)+(1*0)=72 72 % 10 = 2 So 4157-10-2 is a valid CAS Registry Number.
