Maleic anhydride is a white crystalline organic compound with the chemical formula C4H2O3. It is an important industrial chemical, primarily used in the production of unsaturated polyester resins, alkyd resins, and various other chemicals. Maleic anhydride is produced through the oxidation of benzene or butane and is known for its ability to react with various compounds, such as amines and alcohols, to form esters and amides. It is also used in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. Due to its versatile reactivity and applications, maleic anhydride plays a significant role in the chemical industry.
The CAS Registry Mumber 6007-87-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,0 and 7 respectively; the second part has 2 digits, 8 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6007-87: (6*6)+(5*0)+(4*0)+(3*7)+(2*8)+(1*7)=80 80 % 10 = 0 So 6007-87-0 is a valid CAS Registry Number.
