The chemical compound "(3aR,4aC,7aC,8aC)-hexahydro-benzo[1,2-d;5,4-d']bisoxazole-2,6-dione" is a complex organic molecule with a unique structure. It features a hexahydro core, which means it contains six hydrogen atoms bonded to carbon in a cyclic structure. The compound is characterized by the presence of two oxazole rings, which are five-membered heterocyclic compounds containing oxygen and nitrogen. These rings are fused together, forming a bisoxazole structure. The numbering of the carbon atoms in the structure indicates the specific positions of the oxazole rings and the ketone groups (-2,6-dione), which are carbonyl groups (C=O) located at the 2nd and 6th positions of the molecule. The stereochemistry is specified by the prefixes "R" and "C", which denote the configuration of the chiral centers at the 3a and 4a, 7a, and 8a positions, respectively. (3ar,4ac,7ac,8ac)-hexahydro-benzo[1,2-d;5,4-d']bisoxazole-2,6-dione is an example of a highly functionalized and stereospecific organic molecule, which can be found in various applications in the fields of chemistry and pharmaceuticals.
The CAS Registry Mumber 72028-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,2 and 8 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 72028-27: (7*7)+(6*2)+(5*0)+(4*2)+(3*8)+(2*2)+(1*7)=104 104 % 10 = 4 So 72028-27-4 is a valid CAS Registry Number.
