Ethyldithiophosphonic acid S-[4-(1,1-dimethylethyl)phenyl]O-ethyl ester, also known as ethyl 4-(tert-butyl)phenyl ethyl phosphorodithioate, is a chemical compound with the molecular formula C13H21O2PS2. It is a colorless to pale yellow liquid with a density of 1.1 g/cm3 and a boiling point of 130-140°C at 0.1 mm Hg. Ethyldithiophosphonic acid=S-[4-(1,1-dimethylethyl)phenyl]O-ethyl ester is primarily used as an agricultural pesticide, specifically as a systemic fungicide, to protect crops from various fungal diseases. It works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, which ultimately leads to the death of the fungus. Due to its effectiveness and low mammalian toxicity, it is widely used in the agricultural industry to safeguard crops and maintain food production.

329-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 329-21-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 329-21:
(5*3)+(4*2)+(3*9)+(2*2)+(1*1)=55
55 % 10 = 5
So 329-21-5 is a valid CAS Registry Number.
