4645-32-3 Usage
General Description
Dimethyl vinylphosphonate is a chemical compound with the formula C5H9O3P, with a molecular weight of 146.09 g/mol. It is a colorless liquid with a fruity odor and is highly flammable. Dimethyl vinylphosphonate is commonly used as a monomer in the production of polymers and copolymers for various applications, including flame retardants, adhesives, and coatings. It is also used in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Furthermore, dimethyl vinylphosphonate is known to react readily with nucleophiles, such as amines, alcohols, and thiols, making it a versatile building block in organic synthesis. However, it is important to handle dimethyl vinylphosphonate with care, as it is toxic and can cause skin and eye irritation upon contact.
Check Digit Verification of cas no
The CAS Registry Mumber 4645-32-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4645-32:
(6*4)+(5*6)+(4*4)+(3*5)+(2*3)+(1*2)=93
93 % 10 = 3
So 4645-32-3 is a valid CAS Registry Number.
