Biphenylene, 1,4,5,8-tetrachloro-, also known as 1,4,5,8-tetrachlorobiphenylene, is a polychlorinated biphenylene compound with the chemical formula C12H4Cl4. It is a member of the polychlorinated biphenyls (PCBs) family, which are a group of organic compounds consisting of biphenyl molecules with one or more chlorine atoms attached. This specific compound has four chlorine atoms attached to the biphenyl structure, with the chlorine atoms positioned at the 1, 4, 5, and 8 positions. 1,4,5,8-tetrachlorobiphenylene is a colorless solid with low solubility in water and high solubility in organic solvents. It is a persistent organic pollutant (POP) due to its chemical stability, resistance to degradation, and potential for long-range transport in the environment. As a result, it can accumulate in the food chain and pose risks to human health and the environment.

7090-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7090-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7090-43:
(6*7)+(5*0)+(4*9)+(3*0)+(2*4)+(1*3)=89
89 % 10 = 9
So 7090-43-9 is a valid CAS Registry Number.
