133043-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133043-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,4 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133043-81:
(8*1)+(7*3)+(6*3)+(5*0)+(4*4)+(3*3)+(2*8)+(1*1)=89
89 % 10 = 9
So 133043-81-9 is a valid CAS Registry Number.

From Fourfold Functionalized Cyclophanes to Tube-Shaped Molecules
Schroeder, Axel,Karbach, Detlef,Guether, Ralf,Voegtle, Fritz
, p. 1881 - 1888 (2007/10/02)
A series of fourfold functionalized 2,11-dithia- and 2,11-diazacyclophanes 15-17 and 18-22, resp., is prepared by using a new multistep-strategy starting from 7 of m-xylene, respectively.The cyclophanes are used to construct tube-shaped molecules of
