2,2,2-trinitroethyl acetate, also known as tritonol or ethyl trinitrate, is an organic compound with the chemical formula C4H7N3O7. It is a nitrate ester derivative of nitroglycerin, characterized by the presence of three nitro groups attached to the central carbon atom. 2,2,2-trinitroethyl acetate is highly sensitive to shock and friction, making it a powerful explosive. It was historically used in military applications, particularly as a component in certain types of ammunition and explosives due to its high energy content and brisance. However, its use has been largely replaced by safer and more stable explosives in modern times. The compound is also known for its potential health risks, including acute toxicity, and it is considered a hazardous substance requiring careful handling and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 4998-90-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4998-90:
(6*4)+(5*9)+(4*9)+(3*8)+(2*9)+(1*0)=147
147 % 10 = 7
So 4998-90-7 is a valid CAS Registry Number.
