2,6-Dinitro-4-(1-propylbutyl)-phenol, also known as DNP, is a chemical compound with the molecular formula C9H10N2O5. It is an organic compound that is yellow in color and has a crystalline structure. DNP is primarily used as a high explosive, known for its high energy density and sensitivity to shock and friction. It has been historically used in military applications and as a component in some types of detonators. However, due to its extreme sensitivity and potential hazards, DNP is not used as widely today as it once was. The compound is also noteworthy for its role in a tragic incident in history, where it was accidentally used in the production of a glycerin substitute, leading to a disaster known as the Thessaloniki fire in 1930. This event underscored the importance of careful chemical handling and safety measures in industrial processes.
The CAS Registry Mumber 6465-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 5 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6465-62: (6*6)+(5*4)+(4*6)+(3*5)+(2*6)+(1*2)=109 109 % 10 = 9 So 6465-62-9 is a valid CAS Registry Number.
