2,2',6-Trichlor-benzidin, also known as 2,2',6-Trichlorobiphenyl (PCB 28), is a chlorinated organic compound belonging to the polychlorinated biphenyl (PCB) family. PCBs are a group of 209 distinct chemically-related compounds, which were widely used in various industrial applications due to their heat resistance, electrical insulating properties, and chemical stability. However, they have been identified as persistent organic pollutants (POPs) due to their resistance to degradation, potential bioaccumulation in the environment, and potential adverse effects on human health and wildlife. PCB 28, in particular, is a less toxic and less persistent member of the PCB family, but it still poses risks to the environment and human health, particularly through its potential to disrupt the endocrine system and cause developmental, reproductive, and neurological issues.

Check Digit Verification of cas no

The CAS Registry Mumber 2528-63-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2528-63:
(6*2)+(5*5)+(4*2)+(3*8)+(2*6)+(1*3)=84
84 % 10 = 4
So 2528-63-4 is a valid CAS Registry Number.
