3-amino-1-(4-nitro-phenyl)-propane-1,2-diol, also known as Trinitrophenol (TNP), is a chemical compound with the molecular formula C9H10N4O7. It is an organic compound that features a propane backbone with a 4-nitrophenyl group attached to the first carbon, an amino group on the third carbon, and two hydroxyl groups on the first and second carbons. TNP is a yellow crystalline solid that is soluble in water and various organic solvents. It is primarily used as a high explosive and a chemical intermediate in the synthesis of other compounds. Due to its explosive nature, TNP is highly sensitive to shock and friction, making it a potential hazard in handling and storage. It is also known for its ability to form strong, water-soluble complexes with metal ions, which has led to its use in analytical chemistry for the detection and quantification of certain metals.

Check Digit Verification of cas no

The CAS Registry Mumber 7334-81-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7334-81:
(6*7)+(5*3)+(4*3)+(3*4)+(2*8)+(1*1)=98
98 % 10 = 8
So 7334-81-8 is a valid CAS Registry Number.
