(1R,2S,2aS)-2-(4-Methoxy-phenyl)-1-methyl-1,10b-dihydro-2H-cyclobuta[l]phenanthrene-2a-carboxylic acid methyl ester is a complex organic compound with a molecular formula of C22H22O3. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the R, S, and aS configurations at the 1st, 2nd, and 2a positions, respectively. The compound features a cyclobuta[l]phenanthrene core, which is a type of polycyclic aromatic hydrocarbon, and a 4-methoxy-phenyl group attached to the 2nd carbon. The molecule also includes a methyl ester group, indicating the presence of a carbonyl group bonded to an oxygen atom and a methyl group. This chemical structure suggests potential applications in pharmaceuticals or as a synthetic intermediate due to its unique arrangement of functional groups and stereochemistry.
The CAS Registry Mumber 83665-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,6 and 5 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 83665-36: (7*8)+(6*3)+(5*6)+(4*6)+(3*5)+(2*3)+(1*6)=155 155 % 10 = 5 So 83665-36-5 is a valid CAS Registry Number.
