Check Digit Verification of cas no

The CAS Registry Mumber 1312676-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,6,7 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1312676-75:
(9*1)+(8*3)+(7*1)+(6*2)+(5*6)+(4*7)+(3*6)+(2*7)+(1*5)=147
147 % 10 = 7
So 1312676-75-7 is a valid CAS Registry Number.

Salt (LiF regulated fluorescence switching

Sokkalingam, Punidha,Yoo, Jaeduk,Hwang, Hyonseok,Lee, Phil Ho,Jung, Young Mee,Lee, Chang-Hee

, p. 2911 - 2915 (2011)

A supramolecular host-guest complex stimulated by lithium cation and fluoride anion, functioning as reliable fluorescence "Off-On-Off" switching system has been developed. Nonfluorescent, receptor-bound fluorophore is exclusively displaced by second guest, fluoride anion to release thefluorophore that becomes highly fluorescent in guest concentration dependent way. Again, this process is completely reversed upon exposure to Li+. The entire process is an excellent model for fluorescence-based logic system. A reliable fluorescence "Off-On-Off" switching system regulated by lithium cation and fluoride anion has been developed.
