1,4-bis-diazo-butane, also known as bis(1-diazo-1-oxobutan-2-yl)methane, is a chemical compound with the molecular formula C7H10N2O2. It is a colorless, crystalline solid that is sensitive to heat, light, and impact, making it potentially hazardous. 1,4-bis-diazo-butane is primarily used as a blowing agent in the production of foam plastics and as a chemical intermediate in the synthesis of various organic compounds. Due to its instability, it requires careful handling and storage to prevent decomposition and potential explosions.
The CAS Registry Mumber 5239-03-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 9 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5239-03: (6*5)+(5*2)+(4*3)+(3*9)+(2*0)+(1*3)=82 82 % 10 = 2 So 5239-03-2 is a valid CAS Registry Number.
