Check Digit Verification of cas no

The CAS Registry Mumber 123344-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,4 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123344-19:
(8*1)+(7*2)+(6*3)+(5*3)+(4*4)+(3*4)+(2*1)+(1*9)=94
94 % 10 = 4
So 123344-19-4 is a valid CAS Registry Number.

The effects of cyclic terminal groups on the electronic absorption spectra of di- and tri-phenylmethane dyes

Beach, Steven F.,Hepworth, John D.,Jones, Peter,Mason, Donald,Sawyer, John,et al.

, p. 1087 - 1090 (2007/10/02)

The spectral shifts of the first absorption bands brought about by cyclic terminal groups in analogues of Michler's Hydrol Blue, Malachite Green, and Crystal Violet are determined mainly by inductive effects.Dye cations containing terminal pyrrolidino substituents are significantly more stable than those possessing piperidino groups as a result of differences in basicity brought about by a change in size of the saturated heterocyclic ring.
