67651-35-8 Usage
General Description
4-HYDROXY-2',3,3',4',5'-PENTACHLOROBIPHENYL, also known as 4-OH-2,3,3',4',5'-PCB, is a type of polychlorinated biphenyl (PCB). It is a highly toxic and persistent organic pollutant that has been widely used in electrical equipment, hydraulic fluids, and other industrial applications. This chemical has been found to have harmful effects on human health and the environment, including causing cancer, reproductive and developmental disorders, and disrupting the endocrine system. 4-OH-2,3,3',4',5'-PCB is resistant to degradation and can accumulate in soil, water, and living organisms, posing a threat to the ecosystem and human health. Due to its toxic properties, the production and use of PCBs have been banned or restricted in many countries, but they still persist as environmental contaminants.
Check Digit Verification of cas no
The CAS Registry Mumber 67651-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,5 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67651-35:
(7*6)+(6*7)+(5*6)+(4*5)+(3*1)+(2*3)+(1*5)=148
148 % 10 = 8
So 67651-35-8 is a valid CAS Registry Number.
