General Description
2,2',3,3',4,4',5,5'-Octachlorobiphenyl, also known as PCB 209, is a highly toxic and persistent organic pollutant. It is a member of the polychlorinated biphenyl (PCB) group of chemicals, which were widely used in electrical equipment and other industrial applications before their production was banned due to their harmful effects on human health and the environment. Octachlorobiphenyl is a colorless to light-yellow solid with a slightly sweet odor and is insoluble in water. It is classified as a probable human carcinogen and has been linked to a range of health issues, including developmental and reproductive disorders, immune system impairment, and thyroid dysfunction. Due to its persistence and ability to bioaccumulate in the food chain, octachlorobiphenyl continues to be a significant concern in many contaminated sites around the world.
Check Digit Verification of cas no
The CAS Registry Mumber 35694-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,6,9 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 35694-08:
(7*3)+(6*5)+(5*6)+(4*9)+(3*4)+(2*0)+(1*8)=137
137 % 10 = 7
So 35694-08-7 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.
