Propionyl azide, also known as ethanoic azide or propanoic azide, is an organic compound with the chemical formula C2H5CN3. It is a colorless, oily liquid that is highly reactive and sensitive to shock and heat. Propionyl azide is synthesized by the reaction of propionyl chloride with sodium azide, and it is used as a reagent in organic synthesis, particularly in the preparation of various heterocyclic compounds and as a source of the highly reactive nitrene intermediates. Due to its instability and potential to explode, it requires careful handling and storage under controlled conditions.

7139-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7139-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 7139-74:
(6*7)+(5*1)+(4*3)+(3*9)+(2*7)+(1*4)=104
104 % 10 = 4
So 7139-74-4 is a valid CAS Registry Number.
