<3-Oxo-but-1-enyl>-malonsaeure-diethylester, also known as 3-oxo-but-1-enyl malonic acid diethyl ester, is a chemical compound with the molecular formula C10H14O5. It is a derivative of malonic acid, featuring a 3-oxo-but-1-enyl group attached to the malonic acid structure. <3-Oxo-but-1-enyl>-malonsaeure-diethylester is an important intermediate in organic synthesis, particularly in the preparation of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is synthesized through the reaction of diethyl malonate with 3-butyn-2-one, followed by a hydrolysis and decarboxylation process. The compound is a colorless liquid with a density of 1.08 g/cm3 and a boiling point of 280°C. It is soluble in most organic solvents and is sensitive to hydrolysis, which can lead to the formation of 3-oxo-butanal and diethyl malonate. Due to its reactivity, it is often used in the synthesis of various heterocyclic compounds and as a building block for more complex organic molecules.

6465-10-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6465-10-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.Calculate Digit Verification of CAS Registry Number 6465-10:
(6*6)+(5*4)+(4*6)+(3*5)+(2*1)+(1*0)=97
97 % 10 = 7
So 6465-10-7 is a valid CAS Registry Number.
