Check Digit Verification of cas no

The CAS Registry Mumber 503616-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,6,1 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 503616-60:
(8*5)+(7*0)+(6*3)+(5*6)+(4*1)+(3*6)+(2*6)+(1*0)=122
122 % 10 = 2
So 503616-60-2 is a valid CAS Registry Number.

Novel cyanine dyes: Synthesis, characterization and photosensitization- structure correlation

Shindy,El-Maghraby,Eissa

, p. 1061 - 1068 (2002)

Novel furo, thieno and pyrrolo[2,3-b]pyrazole cyanine dyes were synthesized. The structure-photosensitization properties correlation of the dyes were examined in 95% ethanol solution by absorption spectroscopy. The chemical structure of the starting biheterocyclic compounds and their derived cyanine dyes were confirmed by elemental analysis, IR and 1H NMR spectroscopy.
