Check Digit Verification of cas no

The CAS Registry Mumber 701901-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,1,9,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 701901-03:
(8*7)+(7*0)+(6*1)+(5*9)+(4*0)+(3*1)+(2*0)+(1*3)=113
113 % 10 = 3
So 701901-03-3 is a valid CAS Registry Number.

8-Amino-5-ethyl-3-oxido-6-phenylphenanthridinium Betaine, a New Solvatochromic Compound

Finkentey, Johann-Henrich,Zimmermann, Herbert W.

, p. 1 - 6 (2007/10/02)

Synthesis and some properties of 8-amino-5-ethyl-3-oxido-6-phenylphenanthridinium betaine (3) are described.The structure is proved by 1H-NMR and mass spectroscopy.In aqueous solutions 3 is in a pH dependent equilibrium with its conjugated aminophenol 2 and the twice protonated dication 4.The pKa value of the prototropic equilibrium between 3 and 2 at 25 deg C is 7.15.The betaine shows a strong negative solvent effect.Solutions of 3 in aprotoic solvents are blue, in amphiprotonic solvents red to purple.
