31508-00-6 Usage
General Description
2,3',4,4',5-Pentachlorobiphenyl, also known as PCB 126, is one of the most toxic types of Polychlorinated Biphenyls (PCBs). PCBs, including PCB 126, are synthetic organic chemicals that are no longer produced in the U.S. due to their potential to cause serious health effects, but persist in the environment due to their chemical stability. PCB 126 is particularly toxic as it acts like dioxin, which is known to be carcinogenic and detrimental to the immune, reproductive, nervous, and endocrine systems. It is typically found in mixtures with other PCBs and is primarily present in the environment from past releases and disposal of PCB products. Inhalation, ingestion, and skin contact are main routes of exposure to this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 31508-00-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,0 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31508-00:
(7*3)+(6*1)+(5*5)+(4*0)+(3*8)+(2*0)+(1*0)=76
76 % 10 = 6
So 31508-00-6 is a valid CAS Registry Number.
