Dimethyl-phenyl-phosphin-schwefelkohlenstoff-addukt, also known as O,O-dimethyl-O-phenyl-phosphorodithioate or O,O-dimethyl-S-phenyl-phosphorodithioate, is a chemical compound with the molecular formula C9H11O2PS2. It is an organophosphorus compound that features a phosphorus atom bonded to two methyl groups, a phenyl group, and a sulfur atom. Dimethyl-phenyl-phosphin-schwefelkohlenstoff-addukt is often used as a pesticide, particularly as an acaricide, to control mites and ticks in agriculture. It works by inhibiting the acetylcholinesterase enzyme in the nervous system of the target pests, leading to their paralysis and death. Due to its potential health risks and environmental concerns, its use is regulated in many countries.

Check Digit Verification of cas no

The CAS Registry Mumber 1004-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1004-43:
(6*1)+(5*0)+(4*0)+(3*4)+(2*4)+(1*3)=29
29 % 10 = 9
So 1004-43-9 is a valid CAS Registry Number.

Stability of Charge-Transfer Complexes of CS2 with PH3 and Its Derivatives: Ab initio MRSDCI/CASSCF Study

Zahradnik, Rudolf,Jungwirth, Pavel,Urban, Jiri,Polasek, Martin

, p. 1810 - 1816 (1994)

While trialkylamines and dialkyl(phenyl)amines do not react with CS2 in the sense of an addition reaction, the analogous phosphines react smoothly.Attempts to interpret the reaction course on the basis of semiempirical, HF, MP2, and MP4 calculations of energy changes failed completely.To understand why Me3P or Me2PhP react so vigorously (liquid phase, 300 K) with CS2, CASSCF and MRSDCI calculations must be carried out.
