Propanedioic acid, ethylidene-, also known as malonic acid, is a dicarboxylic acid with the chemical formula C3H4O4. It is a colorless, crystalline solid that is soluble in water and slightly soluble in ethanol. Malonic acid is an important organic compound used in the synthesis of various chemicals, such as barbiturates, alkyl malonates, and other pharmaceuticals. It is also used as a precursor in the production of plastics, resins, and other polymers. Malonic acid can be synthesized through various methods, including the Kolbe-Schmitt reaction, which involves the reaction of carbon dioxide with sodium phenoxide. Due to its versatile applications and chemical properties, malonic acid plays a significant role in the chemical industry and pharmaceutical sector.

4473-05-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4473-05-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,7 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4473-05:
(6*4)+(5*4)+(4*7)+(3*3)+(2*0)+(1*5)=86
86 % 10 = 6
So 4473-05-6 is a valid CAS Registry Number.
