The chemical compound "(1R)-O3,O4,O6-triacetyl-O2-phenylcarbamoyl-1-piperidino-1,5-anhydro-D-glucitol" is a complex organic molecule derived from D-glucitol, a sugar alcohol. It features a 1,5-anhydro ring structure, which means that the hydroxyl groups at the 1 and 5 positions are missing, creating a double bond between these carbons. The molecule is further modified with three acetyl groups (acetate esters) at the 3, 4, and 6 positions, which protect the hydroxyl groups at these positions. Additionally, a phenylcarbamoyl group is attached at the 2 position, and a piperidino group is present at the 1 position. (1R)-O3,O4,O6-triacetyl-O2-phenylcarbamoyl-1-piperidino-1,5-anhydro-D-glucitol is a chiral molecule, with the "1R" designation indicating the specific configuration of the molecule at the 1 position. The combination of these functional groups and the chiral center gives the compound its unique properties and potential applications in various fields, such as pharmaceuticals or chemical research.
The CAS Registry Mumber 20147-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,4 and 7 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 20147-90: (7*2)+(6*0)+(5*1)+(4*4)+(3*7)+(2*9)+(1*0)=74 74 % 10 = 4 So 20147-90-4 is a valid CAS Registry Number.
