5160-60-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5160-60-1 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, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5160-60:
(6*5)+(5*1)+(4*6)+(3*0)+(2*6)+(1*0)=71
71 % 10 = 1
So 5160-60-1 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.
