57083-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57083-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,8 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57083-01:
(7*5)+(6*7)+(5*0)+(4*8)+(3*3)+(2*0)+(1*1)=119
119 % 10 = 9
So 57083-01-9 is a valid CAS Registry Number.

Unidirectional threading synthesis of isomer-free [2]rotaxanes
Wang, Qiao-Chun,Ma, Xiang,Qu, Da-Hui,Tian, He
, p. 1088 - 1096 (2006)
The threading of an α-cyclodextrin (α-CyD) by an unsymmetrical dumbbell generally results in two isomeric [2]rotaxanes differing in the orientation of the α-CyD. In this work, two methods have been developed for the unidirectionally threading an α-CyD to
