Propanedioic acid, cyclopentylmethyl-, diethyl ester is a complex organic compound with the chemical formula C13H22O4. It is an ester derivative of propanedioic acid, also known as malonic acid, with a cyclopentylmethyl group attached to the central carbon atom. The diethyl ester functional group is formed by the esterification of the two carboxylic acid groups with ethanol. Propanedioic acid, cyclopentylmethyl-, diethyl ester is characterized by its molecular structure, which consists of a six-membered cyclopentyl ring, a three-carbon chain with two ester groups, and an ethyl group attached to each carboxylic acid. It is a colorless liquid with a specific odor and is insoluble in water but soluble in organic solvents. Propanedioic acid, cyclopentylmethyl-, diethyl ester, is primarily used in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique structural properties and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 1142-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1142-71:
(6*1)+(5*1)+(4*4)+(3*2)+(2*7)+(1*1)=48
48 % 10 = 8
So 1142-71-8 is a valid CAS Registry Number.
