2,4,5,6-tetrachlorobenzene-1,3-dicarboxylic acid is a chemical compound that belongs to the family of tetrachlorobenzene derivatives. It is a white crystalline solid that is not very soluble in water. 2,4,5,6-tetrachlorobenzene-1,3-dicarboxylic acid is mainly used in the production of dyes, pigments, and other industrial products. It is also known to have potential toxic and environmental effects due to its persistence in the environment and its potential to bioaccumulate in organisms. 2,4,5,6-tetrachlorobenzene-1,3-dicarboxylic acid may pose health risks to humans and other organisms if not properly handled and disposed of.
Check Digit Verification of cas no
The CAS Registry Mumber 7401-89-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,0 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7401-89:
(6*7)+(5*4)+(4*0)+(3*1)+(2*8)+(1*9)=90
90 % 10 = 0
So 7401-89-0 is a valid CAS Registry Number.

Electrocarboxylation of chlorinated aromatic compounds
Golinske, Dirk,Voss, Juergen,Adiwidjaja, Gunadi
, p. 862 - 880 (2007/10/03)
Chorinated benzenes (1, 4), biphenyls (6, 9), dibenzofurans (10, 15, 17, 18), 2-chlorodibenzo[1,4]dioxine (24) and 1-chloronaphthalene (26) as well as dibenzofuran (12) and naphthalene (27) themselves were transformed into carboxylic acids by galvanostatic electroreduction in the presence of carbon dioxide ("electrocarboxylation"). Dry DMF was used as solvent, zinc or stainless steel as cathode and magnesium as a sacrificial anode in an undivided cell. Hydrogenation of aromatic rings was not observed. However, reductive addition of two molecules of carbon dioxide to form dihydrodicarboxylic acids, e.g. 22 and 29, occurs in the dibenzofuran and naphthalene series.
