Ethyl-phenyl-phosphinodithioic acid butyl ester, also known as EPPB, is an organophosphorus compound with the chemical formula C12H19O2PS2. It is a colorless to pale yellow liquid with a pungent odor, and it is used as a pesticide, specifically as an acaricide and miticide, to control mites and ticks in agriculture. EPPB works by inhibiting the acetylcholinesterase enzyme in the nervous system of the target pests, leading to their paralysis and death. It is effective against a wide range of pests, including spider mites, tea red spider mites, and other mite species. Due to its potential toxicity and environmental impact, it is important to follow proper application guidelines and safety measures when using EPPB.
The CAS Registry Mumber 6769-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,6 and 9 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6769-83: (6*6)+(5*7)+(4*6)+(3*9)+(2*8)+(1*3)=141 141 % 10 = 1 So 6769-83-1 is a valid CAS Registry Number.
