1642-43-9 Usage
General Description
Triethyl phosphorotetrathioate is a chemical compound commonly used as an insecticide or acaricide. It belongs to the organophosphate insecticides family and is known for its ability to control a wide range of insect pests, including mites, flies, and beetles. triethyl phosphorotetrathioate works by inhibiting the enzyme acetylcholinesterase, which ultimately leads to the insect's paralysis and death. Triethyl phosphorotetrathioate is highly toxic to both insects and humans, and therefore, requires careful handling and application. It has been banned or heavily restricted in several countries due to its potential harm to the environment and human health.
Check Digit Verification of cas no
The CAS Registry Mumber 1642-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1642-43:
(6*1)+(5*6)+(4*4)+(3*2)+(2*4)+(1*3)=69
69 % 10 = 9
So 1642-43-9 is a valid CAS Registry Number.
