Diazenedicarboxylic acid, dipropyl ester, also known as dipropyl azodicarboxylate (DPA), is an organic compound with the chemical formula C7H12N2O4. It is a colorless, oily liquid that is soluble in organic solvents. DPA is widely used as a crosslinking agent in the production of polyurethane foams, as a blowing agent in the plastics industry, and as a reagent in various chemical reactions. It is also employed in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, DPA is considered hazardous and requires proper handling and storage to prevent exposure and potential health risks.

Check Digit Verification of cas no

The CAS Registry Mumber 2787-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2787-39:
(6*2)+(5*7)+(4*8)+(3*7)+(2*3)+(1*9)=115
115 % 10 = 5
So 2787-39-5 is a valid CAS Registry Number.
