Naphthalene, 1,2,5-trinitro-, also known as 1,2,5-trinitronaphthalene (TNN), is a chemical compound with the molecular formula C10H5N3O6. It is a yellow crystalline solid that is derived from naphthalene, a polycyclic aromatic hydrocarbon. TNN is an energetic compound, meaning it has a high energy content and can be used as an explosive or a propellant. It is known for its high density, high melting point, and low sensitivity to impact, making it a potentially useful material in the field of explosives. However, due to its toxicity and environmental concerns, its use is limited and strictly regulated. TNN is also used in research for its properties as a high-energy-density material and as a precursor in the synthesis of other compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 2243-93-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2243-93:
(6*2)+(5*2)+(4*4)+(3*3)+(2*9)+(1*3)=68
68 % 10 = 8
So 2243-93-8 is a valid CAS Registry Number.
