The chemical compound "(3S)-3r,10c-bis-acetoxymethyl-7t,14t-diheptyl-1,8-dioxa-4,11-diaza-cyclotetradecane-2,5,9,12-tetraone" is a complex organic molecule with a unique structure. It features a cyclotetradecane ring, which is a 14-carbon cyclic structure, with two nitrogen atoms incorporated into the ring, creating a diaza compound. The molecule also contains two heptyl (seven-carbon) chains and a 1,8-dioxa bridge, which are oxygen atoms connecting two carbons in the ring. Additionally, it has two acetoxymethyl groups, which are acetate-protected methyl groups, attached to specific carbons in the ring. The "3S" notation indicates that the molecule has a specific stereochemistry at the third carbon, with the hydroxyl group and the acetoxymethyl group on the same side of the molecule when viewed from the audience. (3S)-3r,10c-bis-acetoxymethyl-7t,14t-diheptyl-1,8-dioxa-4,11-diaza-cyclotetradecane-2,5,9,12-tetraone is likely to be a chiral molecule, meaning it has a non-superimposable mirror image, and the "3S" configuration specifies the arrangement of atoms in three-dimensional space.
The CAS Registry Mumber 4273-27-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 3 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4273-27: (6*4)+(5*2)+(4*7)+(3*3)+(2*2)+(1*7)=82 82 % 10 = 2 So 4273-27-2 is a valid CAS Registry Number.
