7,7-Tridecanedicarboxylic acid, also known as undecanedioic acid, is a dicarboxylic acid with the chemical formula C13H24O4. It is a white crystalline solid that is soluble in water and has a molecular weight of 248.33 g/mol. This organic compound is characterized by a 13-carbon alkane chain with two carboxylic acid groups attached at the terminal ends. It is used in the synthesis of various chemicals, such as polyesters, polyamides, and other polymers, and can also be found as an intermediate in the production of certain pharmaceuticals and fragrances. The compound is typically synthesized through the oxidation of alkenes or through the Kolbe-Schmitt reaction, which involves the reaction of carbon dioxide with sodium phenoxide to form the desired dicarboxylic acid.

Check Digit Verification of cas no

The CAS Registry Mumber 4381-78-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4381-78:
(6*4)+(5*3)+(4*8)+(3*1)+(2*7)+(1*8)=96
96 % 10 = 6
So 4381-78-6 is a valid CAS Registry Number.
