Acetonyl-malonic acid, also known as diketo-malonic acid, is a chemical compound with the molecular formula C5H6O5. It is a derivative of malonic acid, where one of the hydrogen atoms is replaced by an acetonyl group (CH3CO). This organic compound is a key intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Acetonyl-malonic acid is a white crystalline solid that is soluble in water and has a melting point of approximately 90°C. It is synthesized through the condensation of acetone with malonic acid in the presence of a catalyst, such as sodium acetate. Due to its versatile reactivity, it is widely used in the chemical industry for the preparation of various esters, amides, and other functionalized molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 4354-89-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,5 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4354-89:
(6*4)+(5*3)+(4*5)+(3*4)+(2*8)+(1*9)=96
96 % 10 = 6
So 4354-89-6 is a valid CAS Registry Number.
