Check Digit Verification of cas no

The CAS Registry Mumber 146903-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 146903-66:
(8*1)+(7*4)+(6*6)+(5*9)+(4*0)+(3*3)+(2*6)+(1*6)=144
144 % 10 = 4
So 146903-66-4 is a valid CAS Registry Number.

On the Structure of Guanylhydrazones Derived from Aromatic Aldehydes

Holzer, Wolfgang,Gyoergydeak, Zoltan

, p. 1163 - 1174 (2007/10/02)

The synthesis of some novel guanylhydrazones derived from aromatic aldehydes (benzylideneaminoguanidines) is described.Structural assignments of these compounds as well as of some already known congeners, particularly with respect to the configuration of the HC=N double bond, were achieved using (1)H- and (13)C-NMR data as well as homonuclear NOE difference spectroscopy.Keywords.Benzaldehyde guanylhydrazones, substituted Benzylideneaminoguanidines; (1)H-NMR spectroscopy; (13)C-NMR spectroscopy; NOE Difference spectroscopy.
