478491-50-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478491-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,4,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 478491-50:
(8*4)+(7*7)+(6*8)+(5*4)+(4*9)+(3*1)+(2*5)+(1*0)=198
198 % 10 = 8
So 478491-50-8 is a valid CAS Registry Number.

Photoluminescent supramolecular polymers: Metal-ion directed polymerization of terpyridine-functionalized perylene bisimide dyes
Dobrawa, Rainer,Wuerthner, Frank
, p. 1878 - 1879 (2002)
Perylene bisimide dyes bearing one and two 2,2′:6′,2″-terpyridine receptor groups were prepared and the structural and optical properties of their Zn2+ complexes were investigated by 1H NMR and fluorescence experiments.
