α-Chlorobis(pentachlorophenyl)methane, also known as pentachlorophenylmethyl chloride, is a chemical compound with the formula C13Cl10H. It is a derivative of pentachlorophenol, where one hydrogen atom is replaced by a chloromethyl group. α-chlorobis(pentachlorophenyl)methane is characterized by its high chlorine content, which contributes to its stability and resistance to degradation. It has been used as a fungicide and wood preservative due to its ability to protect against decay and insect damage. However, its high toxicity and persistence in the environment have led to concerns about its impact on human health and the ecosystem, resulting in its restriction or ban in many countries.

Check Digit Verification of cas no

The CAS Registry Mumber 33119-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,1 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33119-38:
(7*3)+(6*3)+(5*1)+(4*1)+(3*9)+(2*3)+(1*8)=89
89 % 10 = 9
So 33119-38-9 is a valid CAS Registry Number.
