67442-71-1 Usage
General Description
Ethanone, 1,1'-(1,5-pentanediyldi-4,1-phenylene)bis[2-chloro- is a chemical compound that consists of a central pentane chain with two benzene rings on either end. The two chlorine atoms are attached to the benzene rings, resulting in a symmetric structure. Ethanone, 1,1'-(1,5-pentanediyldi-4,1-phenylene)bis[2-chloro- is primarily used in the production of polymers, resins, and other materials in the chemical industry. It can also be found in certain pharmaceuticals and agricultural chemicals. The presence of chlorine atoms makes this compound a potential hazard to human health and the environment, requiring careful handling and disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 67442-71-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,4 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67442-71:
(7*6)+(6*7)+(5*4)+(4*4)+(3*2)+(2*7)+(1*1)=141
141 % 10 = 1
So 67442-71-1 is a valid CAS Registry Number.
