689271-69-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 689271-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,9,2,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 689271-69:
(8*6)+(7*8)+(6*9)+(5*2)+(4*7)+(3*1)+(2*6)+(1*9)=220
220 % 10 = 0
So 689271-69-0 is a valid CAS Registry Number.

Shuttling through anion recognition
Keaveney, Claire M.,Leigh, David A
, p. 1222 - 1224 (2007/10/03)
A negative response: Anion formation induces translocation of the macrocycle in a molecular shuttle (see picture). Shuttling only occurs in polar solvents and is unaffected by the nature of the countercation or the presence of other anions.
