18708-87-7 Usage
General Description
Cis-Chlorfenvinphos is a chemical compound that belongs to the organophosphate class of pesticides. It is commonly used as an insecticide to control a wide range of pests in agriculture. Cis-Chlorfenvinphos works by disrupting the nervous system of insects, ultimately leading to paralysis and death. It is known for its high toxicity to both insects and mammals, and has been classified as a hazardous chemical by regulatory agencies. Due to its potential health and environmental risks, the use of cis-Chlorfenvinphos has been restricted or banned in many countries. It is important to handle and dispose of this chemical with caution, and to seek alternative methods for pest control that are less harmful to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 18708-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,0 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18708-87:
(7*1)+(6*8)+(5*7)+(4*0)+(3*8)+(2*8)+(1*7)=137
137 % 10 = 7
So 18708-87-7 is a valid CAS Registry Number.

Preparation of carbon-14 labeled organophosphate pesticides: Chlorfenvinphos
Fudala, Louise,Lewin, Anita H.
, p. 261 - 266 (2007/10/03)
Synthesis of [vinyl-14C]chlorfenvinphos, utilizing [14C]iodomethane as the source of the label, was accomplished in 28% radiochemical yield by the methylation of 2,4-dichlorobenzoyl chloride, chlorination of the resulting [14C]-2,4-dichloroacetophenone, and condensation of the product with triethylphosphite. The product, isolated as a mixture of E and Z isomere (3.6 and 96.3%, respectively), was obtained in >99% purity and had specific activity 20 mCl/mmol.
