5160-55-4 Usage
General Description
2,4,6-trinitrophenol, also known as picric acid, is a highly explosive and toxic compound often used in the production of dyes, pharmaceuticals, and explosives. It is primarily used as an intermediate in the synthesis of various chemicals and in some industrial processes. 2-methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH) commonly found in coal tar and petroleum. It is used as a solvent and raw material in the production of dyes, resins, and pharmaceuticals. When combined in a 1:1 ratio, 2,4,6-trinitrophenol and 2-methylnaphthalene form a mixture with potential applications in industrial processes and chemical synthesis. However, their toxic, explosive, and flammable properties require careful handling and consideration of safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 5160-55-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5160-55:
(6*5)+(5*1)+(4*6)+(3*0)+(2*5)+(1*5)=74
74 % 10 = 4
So 5160-55-4 is a valid CAS Registry Number.

A Computerised Least Square Method for Determination of Stability Constants of 1:1 Molecular Complexes and Chemical Shift of Pure Complexes from Nuclear Magnetic Resonance Data
Seal, B. K.,Mukherjee, A. K.
, p. 413 - 415 (2007/10/02)
A computerised method utilising nuclear magnetic resonance data has been developed for the determination of stability constants of 1:1 molecular complexes.It is based on the principle of least squares in which the coefficients are adjusted under a constraint with the help of Lagrange's method of undetermined multipliers.The method utilises the complete expression for equilibrium constant and is mathematically rigorous, straightforward, non-iterative and requires very little computer time.
