20834-66-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20834-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20834-66:
(7*2)+(6*0)+(5*8)+(4*3)+(3*4)+(2*6)+(1*6)=96
96 % 10 = 6
So 20834-66-6 is a valid CAS Registry Number.

A highly selective fluorescent probe for thiophenols
Jiang, Wei,Fu, Qingquan,Fan, Hongyou,Ho, Joe,Wang, Wei
, p. 8445 - 8448 (2007)
A rapid response to thiophenols is obtained with probe 1 (see scheme), which induces a significant (> 50-fold) fluorescence enhancement as a result of cleavage of the electron-withdrawing moiety, thus generating strongly fluorescent molecule 2. No fluores
