4245-37-8 Usage
General Description
Vinyl Methacrylate, also known as VMA or Methacrylic Acid, is a colorless liquid with a sweet, pungent odor. As a monomer, it is widely used in the production of polymers and co-polymers, among other industrial processes. These materials are found in an array of commercial products, including coatings, adhesives, sealants, oil additives, and textiles. While it is a valuable industrial chemical, Vinyl Methacrylate has potential harmful effects. It is classified as an irritant and can cause severe skin burns and eye damage. There's also concern about its potential environmental impact, as it is considered toxic to aquatic life.
Check Digit Verification of cas no
The CAS Registry Mumber 4245-37-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,4 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4245-37:
(6*4)+(5*2)+(4*4)+(3*5)+(2*3)+(1*7)=78
78 % 10 = 8
So 4245-37-8 is a valid CAS Registry Number.

Process for Preparing Vinyl Carboxylates
-
Page/Page column 6, (2009/01/24)
The present invention relates to a process for preparing vinyl carboxylates, wherein a carboxylic acid is reacted with an alkyne compound in the presence of a catalyst which is selected from carbonyl complexes, halides and oxides of rhenium, of manganese, of tungsten, of molybdenum, of chromium and of iron and rhenium metal at a temperature of ≦300° C. The process gives the desired vinyl esters with high yield.
