Check Digit Verification of cas no

The CAS Registry Mumber 634558-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,5,5 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 634558-52:
(8*6)+(7*3)+(6*4)+(5*5)+(4*5)+(3*8)+(2*5)+(1*2)=174
174 % 10 = 4
So 634558-52-4 is a valid CAS Registry Number.

Syntheses and UV-visible spectroscopic properties of two new hydrophilic 2,6-di(carbamoyl)-substituted solvatochromic pyridinium N-phenolate betaine dyes

Reichardt, Christian,Roechling, Andreas,Schaefer, Gerhard

, p. 682 - 690 (2007/10/03)

Synthesis and negative solvatochromism of two 2,6-di(carbamoyl) -substituted pyridinium N-phenolate betaines dyes were investigated. The exceptionally large negative solvatochromism of the standard betaine dye was used to establish a UV-Vis spectroscopically derived scale of solvent polarity. It was found that the primary indicator dye was sufficiently soluble in most organic solvents.
