Check Digit Verification of cas no

The CAS Registry Mumber 140401-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,0 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140401-63:
(8*1)+(7*4)+(6*0)+(5*4)+(4*0)+(3*1)+(2*6)+(1*3)=74
74 % 10 = 4
So 140401-63-4 is a valid CAS Registry Number.

Substituent effects. 14. Anomalous dissociation constants in water-organic solvent mixtures: benzylammonium ions and related systems

Hoefnagel, A. J.,Vos, R. H. de,Wepster, B. M.

, p. 22 - 28 (1992)

Thermodynamic dissociation constants in various water-organic solvent mixtures are given for benzylammonium, benzyldialkylammonium, and (2-phenylethyl)ammonium ions.Deviations from the Hammett equation (Eqn. 1) are similar to those observed for carboxylic acids, but of opposite sign.The extended Hammett equation (Eqn. 3), containing the hydrophobic constant, ?, yields good correlations.Derived secondary normal sigma values are exemplified.
