30365-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30365-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,3,6 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 30365-83:
(7*3)+(6*0)+(5*3)+(4*6)+(3*5)+(2*8)+(1*3)=94
94 % 10 = 4
So 30365-83-4 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.
