Butadiene monoepoxide, also known as 1,2-epoxybutene or butylene oxide, is a colorless, highly reactive organic compound with the chemical formula C4H6O. It is a cyclic ether and an epoxide, formed by the addition of an oxygen atom to the double bond of butadiene. This molecule is a toxic and unstable intermediate in the production of various chemicals, such as synthetic rubber and plastics. Due to its reactivity, it can easily undergo further reactions, making it a valuable building block in the synthesis of other compounds. However, it is also a known carcinogen and mutagen, posing significant health risks if not handled properly.

930-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 930-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 930-72:
(5*9)+(4*3)+(3*0)+(2*7)+(1*2)=73
73 % 10 = 3
So 930-72-3 is a valid CAS Registry Number.

210. Cycloaddition of 2H-Pyran-2-thiones with Nitroso Derivatives. An Unexpected Cycloaddition-Rearrangement Reaction

Defoin, Albert,Augelmann, Gerard,Fritz, Hans,Geffroy, Guillaume,Schmidlin, Christian,Streith, Jacques

, p. 1998 - 2014 (2007/10/02)

Reaction of pyran-2-thiones 4 with nitroso derivatives led surprisingly to type-8 (19) adducts which proved to be isomeric with the initially expected primary Diels-Alder cycloadducts 5.Methyl 2-thioxo-2H-pyran-5-carboxylate (4f), when reacted with nitros
