3-(4-chlorophenyl)-glutaric acid monomethyl ester is a chemical compound with the molecular formula C12H13ClO4. It is a derivative of glutaric acid, featuring a 4-chlorophenyl group attached to the third carbon of the glutaric acid backbone. The monomethyl ester functional group is present, indicating that one of the carboxylic acid groups has been esterified with a methyl group. 3-(4-chlorophenyl)-glutaric acid monomethyl ester is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique structural properties. It is a white crystalline solid and is typically handled with care due to its potential reactivity and the presence of a chlorine atom, which can affect its stability and reactivity profile.

Check Digit Verification of cas no

The CAS Registry Mumber 5045-65-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5045-65:
(6*5)+(5*0)+(4*4)+(3*5)+(2*6)+(1*5)=78
78 % 10 = 8
So 5045-65-8 is a valid CAS Registry Number.

Enzymatic desymmetrization of 3-arylglutaric acid anhydrides

Fryszkowska, Anna,Komar, Marta,Koszelewski, Dominik,Ostaszewski, Ryszard

, p. 2475 - 2485 (2005)

Optically active (R)- and (S)-3-arylglutaric acid monoesters 3 were synthesized in quantitative yields and good stereoselectivities by lipase-catalyzed desymmetrization of the corresponding 3-arylglutaric anhydrides 2 with alcohols. It was observed that the stereochemical outcome of the reaction was influenced by the substituents present on the aromatic ring. The influence of the enzyme, alcohol, and solvent was systematically examined. Absolute configurations of the monoesters 3 were assigned by chemical correlation to corresponding lactones 4.
