Propanedioic acid, (2-methyl-2-propenyl)-, also known as 2-methyl-2-propenylidenedioic acid or 2-methyl-2-propenylidenemalonic acid, is a chemical compound with the molecular formula C6H8O4. It is a dicarboxylic acid, meaning it contains two carboxylic acid groups (-COOH) in its structure. The compound is characterized by a 2-methyl-2-propenyl group (also known as an isopropenyl group) attached to the central carbon atom of the propanedioic acid backbone. This organic compound is used as an intermediate in the synthesis of various chemicals, pharmaceuticals, and polymers. It is typically synthesized through the reaction of acetone with chloroacetic acid or by the condensation of acetone with malonic acid. Due to its reactive nature, it is often used in the preparation of esters, amides, and other derivatives, which find applications in various industries.
The CAS Registry Mumber 1575-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 5 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1575-68: (6*1)+(5*5)+(4*7)+(3*5)+(2*6)+(1*8)=94 94 % 10 = 4 So 1575-68-4 is a valid CAS Registry Number.
