Description
Dodecanedioic acid, also known as dodecanedioic acid or adipinic acid, is a dicarboxylic acid with the chemical formula HOOC-(CH2)10-COOH. It is a white crystalline solid that is soluble in water and has a melting point of around 148°C. Dodecanedioic acid is produced by the fermentation of long-chain alkanes using a specific strain of Candida tropicalis. It is used in the production of various materials, including nylon, polyamides, coatings, adhesives, greases, polyesters, dyestuffs, detergents, flame retardants, and fragrances.

Preparation
Dodecanedioic acid is prepared from cyc1ododecene (obtained from butadiene)
by methods which are entirely analogous to those used to prepare
adipic acid from benzene. The cyclododecene is reduced to
cyclododecane, which is oxidized firstly to a mixture of cyc1ododecanol and
cyclododecanone and then to dodecanedioic acid. Dodecanedioic acid is a
colourless crystalline solid, m.p. 129°C.
Purification Methods
Crystallise the dioic acid from water, 75% or 95% EtOH (solubility is 10%), or glacial acetic acid. [Beilstein 2 IV 2126.]
Check Digit Verification of cas no
The CAS Registry Mumber 693-23-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 693-23:
(5*6)+(4*9)+(3*3)+(2*2)+(1*3)=82
82 % 10 = 2
So 693-23-2 is a valid CAS Registry Number.
