Check Digit Verification of cas no
The CAS Registry Mumber 201140-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,1,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 201140-64:
(8*2)+(7*0)+(6*1)+(5*1)+(4*4)+(3*0)+(2*6)+(1*4)=59
59 % 10 = 9
So 201140-64-9 is a valid CAS Registry Number.

Self-assembled [2]catenane in trapezoidal metallacycles with [Cp?Ir]-corners
Liu, Naifang,Huang, Sheng-Li,Liu, Xiaogang,Luo, He-Kuan,Hor, T. S. Andy
, p. 12802 - 12805 (2017)
A series of trapezoidal metallacycles were synthesized by the selective combination of a rigid with a flexible arm. [2]Catenane 3 was obtained by self-assembly when the cavity size of the trapezoidal rings was optimised.
