3421-67-8 Usage
General Description
2,3,5,6-tetrachlorobenzene-1,4-dicarbaldehyde is a chemical compound that belongs to the family of benzene dicarbaldehyde derivatives. It is a highly toxic and environmentally hazardous substance that is commonly used in industrial and research settings as a precursor for the synthesis of various organic compounds. Its chemical structure consists of a benzene ring with four chlorine atoms attached to different positions, as well as two aldehyde functional groups at the 1 and 4 positions on the benzene ring. Due to its toxic nature and potential for environmental harm, strict safety measures and handling protocols are required when working with this compound. Its use is largely regulated and restricted to specialized applications in controlled environments.
Check Digit Verification of cas no
The CAS Registry Mumber 3421-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,2 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3421-67:
(6*3)+(5*4)+(4*2)+(3*1)+(2*6)+(1*7)=68
68 % 10 = 8
So 3421-67-8 is a valid CAS Registry Number.

, p. 101 - 104 (2007/10/03)
A new route for the synthesis of 2,4,5,6-tetrachloroisophthalic and 2,3,5,6-tetrachloro-terephthalic aldehydes from the corresponding tetrachlorobenzenes was developed. The method involves dichloromethylation of the initial compounds with chloroform in th
