Check Digit Verification of cas no

The CAS Registry Mumber 915706-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,5,7,0 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 915706-57:
(8*9)+(7*1)+(6*5)+(5*7)+(4*0)+(3*6)+(2*5)+(1*7)=179
179 % 10 = 9
So 915706-57-9 is a valid CAS Registry Number.

An organic white light-emitting fluorophore

Yang, Youjun,Lowry, Mark,Schowalter, Corin M.,Fakayode, Sayo O.,Escobedo, Jorge O.,Xu, Xiangyang,Zhang, Huating,Jensen, Timothy J.,Fronczek, Frank R.,Warner, Isiah M.,Strongin, Robert M.

The synthesis of new benzo[a]- and [b]xanthene dye frameworks is described. A unique benzo[a]xanthene, seminaphtho[a]fluorone (SNAFR-1), is studied in a variety of media. The optimization of solution parameters and excitation wavelengths allows SNAFR-1 to display red, green, and blue emission bands of approximately equal intensities and also to produce white light. Ratiometric red (anion) and green (neutral) emissions are observed upon varying solution pH. A pH-independent violet-blue emission band is due to the addition of nucleophiles to the benzylic carbon of SNAFR-1.
