2-((R)-1-Methyl-4-oxo-cyclohex-2-enyl)-malonic acid diethyl ester is a complex organic compound with the molecular formula C15H20O6. It is a derivative of malonic acid, featuring a cyclohex-2-enyl ring with a methyl group and a carbonyl group. The compound is characterized by its chiral center, indicated by the "R" configuration, which influences its stereochemistry. This specific arrangement of atoms is crucial for its reactivity and potential applications in the synthesis of various pharmaceuticals and other organic compounds. The diethyl ester group suggests that it is a lipophilic molecule, which may affect its solubility and biological activity. This chemical is typically used as an intermediate in organic synthesis, particularly in the preparation of complex molecules that require the cyclohexenyl moiety.

Check Digit Verification of cas no

The CAS Registry Mumber 78398-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,9 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78398-31:
(7*7)+(6*8)+(5*3)+(4*9)+(3*8)+(2*3)+(1*1)=179
179 % 10 = 9
So 78398-31-9 is a valid CAS Registry Number.

OPTICALLY ACTIVE TRICARBONYL(CYCLOHEXADIENYL)IRON(1+) SALTS : SYNTHETIC EQUIVALENTS TO SPATIALLY DIRECTED ORGANIC CATIONS

Birch, Arthur J.,Stephenson, G. Richard

, p. 779 - 782 (1981)

Optically active tricarbonyl(cyclohexadienyl)iron(1+) salts I, II and III are examples of olefin complexes with molecular asymmetry due to coordination with a transition metal.Their reactions serve to direct the eventual specific formation of a new chiral centre of known absolute configuration.The absolute configuration of the 2-methoxy-5-methyl salt I is defined and its application to the asymmetric synthesis of γ-disubstituted cyclohexanones is described.
