Check Digit Verification of cas no

The CAS Registry Mumber 93316-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,1 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93316-25:
(7*9)+(6*3)+(5*3)+(4*1)+(3*6)+(2*2)+(1*5)=127
127 % 10 = 7
So 93316-25-7 is a valid CAS Registry Number.

Hydrogen bond induced fluorescence recovery of coumarin-based sensor system

Huang, Xiaobo,Dong, Yu,Huang, Qianwen,Cheng, Yixiang

, p. 3822 - 3825 (2013)

Two coumarin-type fluorescent sensors were synthesized and their fluorescence response to pH value was investigated. The fluorescence intensity of sensor 3 and sensor 4 is obviously enhanced along with the increase of pH from 7 to 12 and the reduction of
