71363-52-5 Usage
Uses
Dimethylvinphos is a moderately persistent insecticide
with contact and stomach action and is used to
control stem borers and leaf rollers in rice with a
dust formulation.
Metabolism
The main
degradation route in mammals is O-demethylation to
desmethyl dimethylvinphos, which is hydrolyzed to 2,2,4-
trichloroacetophenone.
Toxicity evaluation
The acute oral LD50 for rats is
155–210 mg/kg. Inhalation LC50 (4 h) for male and
female rats is 970–1189 and >4900 mg/m3 air.
Check Digit Verification of cas no
The CAS Registry Mumber 71363-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,3,6 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71363-52:
(7*7)+(6*1)+(5*3)+(4*6)+(3*3)+(2*5)+(1*2)=115
115 % 10 = 5
So 71363-52-5 is a valid CAS Registry Number.

REACTIONS OF 2,4- AND 2,6-DICHLOROPHENACYLIDENE HALIDES WITH TRIALKYLPHOSPHITES IN PROTIC SOLVENTS. DIRECT EVIDENCE FOR THE "ENOLATE ANION" PATHWAY

The reactions of 2,6-dichlorophenacyl and 2,6-dichlorophenacylidene chlorides and bromides with trimethyl and triethyl phosphites have been investigated.The reactivity of 2,6-dichlorophenacylidene chloride and bromide towards trialkyl phosphites was compared with that of 2,4-dichlorophenacylidene chloride and bromide.The influence of methanol, acting as a model protic solvent, on the above mentioned processes has also benn investigated.The mechanism of Perkow reaction of sterically hindered α-haloketones with bulky substituents around the carbonyl center is discussed.
