Phosphonodithioic acid, methyl-, S,S-diethyl ester, also known as Fenthion, is an organophosphorus compound widely used as an insecticide and acaricide. It is a colorless to pale yellow liquid with a strong, pungent odor. Fenthion is effective against a broad spectrum of pests, including insects, mites, and ticks, and is commonly applied in agriculture, horticulture, and veterinary medicine. The chemical has a molecular formula of C10H15O2PS3 and a molecular weight of 278.34 g/mol. It is highly toxic to aquatic life and should be used with caution to minimize environmental impact. Fenthion's mode of action involves inhibiting acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system of target pests, causing paralysis and death. Due to its toxicity and potential health risks, proper safety measures and regulations must be followed during its application and handling.

Check Digit Verification of cas no

The CAS Registry Mumber 995-88-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 995-88:
(5*9)+(4*9)+(3*5)+(2*8)+(1*8)=120
120 % 10 = 0
So 995-88-0 is a valid CAS Registry Number.

REACTIONS OF O-(ALKYLCHLOROFORMOIMINO)-TRICHLOROMETHYLPHOSPHORANES WITH S-NUCLEOPHILES

Lyashenko, Yu. E.,Sokolov, V. B.

, p. 153 - 162 (2007/10/02)

Interactions of O-(alkylchloroformoimino)trichloromethylphosphoranes with hydrogen sulfide and mercaptans are reported; interaction with 2-mercaptoethanol is discussed and activation of the chlorine at a sp2 hybridized carbon by means of the phosphorane fragment is demonstrated in the substitution reactions with S-nucleophiles; the method of P=S bond formation in chlorophosphoranes by means of the reaction with thioacetic acid is suggested; some derivatives of O-alkylchloroformooximes are described. Key words: O-(alkylchloroformoimino)trichloromethylphosphoranes; O-(alkylchloroformoimino)chloromethylthionophosphonates; O-(alkylchloroformoimino)-O-alkylmethylthionophosphonates; bis(O-methylchloroformoimino)methylphosphonate; O-chloromethylphosphonate; O-(methyl-S-acetylformoimino)chloromethylthionophosphonate.
