General Description
2,2',3,3',4,4',5,5',6-NONACHLOROBIPHENYL is a chemical compound that belongs to the group of polychlorinated biphenyls (PCBs). It is a persistent organic pollutant that was widely used in industrial and commercial applications until its production was banned due to its harmful effects on human health and the environment. 2,2',3,3',4,4',5,5',6-NONACHLOROBIPHENYL is toxic and can accumulate in the fatty tissues of organisms, leading to a range of health issues including cancer, reproductive and developmental problems, and damage to the immune and nervous systems. It is highly resistant to degradation and can persist in the environment for many years, posing a risk to wildlife and human populations. Efforts are being made to limit and clean up the environmental contamination caused by this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 40186-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,8 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40186-72:
(7*4)+(6*0)+(5*1)+(4*8)+(3*6)+(2*7)+(1*2)=99
99 % 10 = 9
So 40186-72-9 is a valid CAS Registry Number.

METHOD FOR SEPARATING AND CLEANING UP POLYHALOGENATED BIPHENYLS
-
Page/Page column 20-26, (2008/06/13)
The method for separating and cleaning up polyhalogenated biphenyls (PHBs) is characterized by comprising the following three steps: (1) the step of bringing a sample containing PHBs into contact with a fibrous activated carbon; (2) the step of washing the fibrous activated carbon with hexanes; and (3) the step of eluting PHBs from the fibrous activated carbon.
