(E)-Diethyldiazene N,N'-dioxide, also known as diethyl azodicarboxylate (DEAD), is an organic compound with the chemical formula C6H10N2O2. It is a colorless, oily liquid that is widely used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Wittig reaction and other related reactions. DEAD is a powerful reagent for the generation of ylides and is often used in the synthesis of alkenes, cyclopropanes, and other complex organic molecules. It is also known for its ability to act as a mild oxidizing agent and a dehydrating agent. Due to its reactivity, it is important to handle DEAD with care, as it can be sensitive to heat and moisture.
The CAS Registry Mumber 3378-48-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,7 and 8 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3378-48: (6*3)+(5*3)+(4*7)+(3*8)+(2*4)+(1*8)=101 101 % 10 = 1 So 3378-48-1 is a valid CAS Registry Number.
