1,3-Benzenedicarboxylic acid, 5-cyclohexyl-2-hydroxy, diethyl ester is a complex organic compound with the chemical formula C20H24O6. It is a derivative of 1,3-benzenedicarboxylic acid, also known as phthalic acid, which has two ester groups attached to it. The compound features a cyclohexyl group at the 5-position and a hydroxyl group at the 2-position, with diethyl ester groups at both ends. This chemical is primarily used as a monomer in the production of various polymers, such as polyesters and polyamides, due to its unique structure and properties. It is also found in some pharmaceuticals and other industrial applications. The compound is synthesized through a series of chemical reactions, often involving the esterification of the corresponding diacid with ethanol in the presence of an acid catalyst.

Check Digit Verification of cas no

The CAS Registry Mumber 90253-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90253-19:
(7*9)+(6*0)+(5*2)+(4*5)+(3*3)+(2*1)+(1*9)=113
113 % 10 = 3
So 90253-19-3 is a valid CAS Registry Number.

Syntheses with Aliphatic Dialdehydes, XXXVIII. - Synthesis and Properties of Cycloalkylmalonaldehydes

Reichardt, Christian,Ferwanah, Abdel-Rahman,Pressler, Wilfried,Yun, Kyeong-Yeol

, p. 649 - 679 (2007/10/02)

Vilsmeier formylation of cycloalkyl-substituted enol ethers (7,14a - c,23) yields the cycloalkylmalonaldehydes 1 - 5 for the first time.In solution 1 - 5 exist in the (E)-s-(E) enol form as vinylogous carboxylic acids.The reaction of 1 - 5 with suitable electrophiles and nucleophiles leads to cycloalkyl-substituted open-chain (29,30), carbocyclic (31) as well as heterocyclic compounds (32-40) with peculiar properties due to the presence of the lipophilic cycloalkyl group.
