83671-20-9 Usage
General Description
4-(2,2-Dichlorovinyl)phenol, also known as DCP, is a synthetic chemical compound that is a derivative of phenol. It is classified as a chlorinated aromatic compound and is widely used as an intermediate in the production of various chemicals, such as herbicides, insecticides, and fungicides. DCP is known to have toxicological effects on the environment and human health, with potential carcinogenic, mutagenic, and teratogenic properties. It is also a persistent organic pollutant and has been listed as a priority substance under the European Water Framework Directive. Due to its hazardous properties, there are strict regulations and guidelines for its handling, use, and disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 83671-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83671-20:
(7*8)+(6*3)+(5*6)+(4*7)+(3*1)+(2*2)+(1*0)=139
139 % 10 = 9
So 83671-20-9 is a valid CAS Registry Number.
