203645-53-8 Usage
General Description
2,2-dichlorovinyl bis(trideuteriomethyl) phosphate is a chemical compound that is used as a flame retardant and plasticizer in various industrial applications. It is a phosphorus-containing compound that contains two chlorine atoms, two vinyl groups, and two trideuteriomethyl groups. 2,2-dichlorovinyl bis(trideuteriomethyl) phosphate is commonly used in the production of polymers and can help to reduce the flammability of materials. However, the use of this chemical has been subject to some controversy due to its potential toxic effects and environmental impact. As a result, there is ongoing research and regulation to ensure its safe and responsible use in industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 203645-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,6,4 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 203645-53:
(8*2)+(7*0)+(6*3)+(5*6)+(4*4)+(3*5)+(2*5)+(1*3)=108
108 % 10 = 8
So 203645-53-8 is a valid CAS Registry Number.

Paragraph 0069; 0070; 0073; 0074, (2016/10/09)
The invention relates to a synthesis method of a stable isotope deuterium-labeled organophosphorus insecticide. The synthesis method comprises the steps of: making stable isotope deuterium-labeled or natural abundance methyl alcohol react with phosphorus trichloride to generate a stable isotope deuterium-labeled dimethyl phosphite or trimethyl phosphite, and then making the stable isotope deuterium-labeled dimethyl phosphite or trimethyl phosphite react with stable isotope deuterium-labeled or natural abundance trichloracetic aldehyde to obtain the stable isotope deuterium-labeled organophosphorus insecticide. Compared with the prior art, the stable isotope deuterium-labeled trichlorphon or dichlorvos provided by the invention has the advantages that the chemical purity reaches above 98.0 percent and the isotope abundance reaches above 98.0 percent atomD after being separated and purified, thus fully meeting the demand on residue detection in the field of food safety.
