The chemical compound "(rac.-1R,2S,3S) methyl 1,2-epoxy-3-methyl-4,4-dioxyethylene-cyclohexane-1-carboxylate" is a complex organic molecule with a unique structure. It features a cyclohexane ring, which is a six-carbon ring structure, with a methyl group attached to the 3rd carbon. The 1,2-epoxy group indicates the presence of an oxirane ring, a three-membered ring containing an oxygen atom, which is connected to the cyclohexane ring. Additionally, the compound has two ether groups (-O-) attached to the 4th carbon of the cyclohexane, forming a 4,4-dioxyethylene moiety. The molecule is a racemic mixture, meaning it contains equal amounts of both the R and S enantiomers, which are mirror images of each other. The compound is also an ester, with a carboxylate group (-COO-) attached to the methyl group. This chemical is known for its potential applications in various fields, including pharmaceuticals and materials science, due to its specific stereochemistry and functional groups.
The CAS Registry Mumber 83957-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 83957-07: (7*8)+(6*3)+(5*9)+(4*5)+(3*7)+(2*0)+(1*7)=167 167 % 10 = 7 So 83957-07-7 is a valid CAS Registry Number.
