Check Digit Verification of cas no

The CAS Registry Mumber 1293911-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,9,1 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1293911-75:
(9*1)+(8*2)+(7*9)+(6*3)+(5*9)+(4*1)+(3*1)+(2*7)+(1*5)=177
177 % 10 = 7
So 1293911-75-7 is a valid CAS Registry Number.

Off-on-off luminescent switching of a dye containing imidazo[4, 5-f][1, 10]phenanthroline

Zhang, Hai Guang,Tao, Xu Tang,Chen, Kao Shan,Yuan, Chun Xue,Yan, Shi Na,Jiang, Min Hua

, p. 647 - 650 (2011)

A new acid-base fluorescent switch containing both imidazo[4,5-f][1,10]- phenanthroline and triphenylamine groups has been synthesized. Its fluorescence emissions and absorptions can be reversibly changed through protonation/ deprotonation of imidazole and amine moiety by controlling the intramolecular charge transfer (ICT) process, leading to off-on-off fluorescent molecular switching.
