Description
Tetrachloroterephthalonitrile (TCTPN) is a dinitrile derivative and an isomer of chloranil. It is characterized by its halogen bond, which has been studied using 35Cl solid-state NMR.
Uses
Used in Chemical Synthesis:
Tetrachloroterephthalonitrile is used as a chemical intermediate for synthesizing 2-aminotrifluoroterephthalonitriles. This application is significant in the development of new compounds and materials with potential applications in various industries.
Check Digit Verification of cas no
The CAS Registry Mumber 1897-41-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1897-41:
(6*1)+(5*8)+(4*9)+(3*7)+(2*4)+(1*1)=112
112 % 10 = 2
So 1897-41-2 is a valid CAS Registry Number.
