Check Digit Verification of cas no
The CAS Registry Mumber 242128-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,2,1,2 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 242128-45:
(8*2)+(7*4)+(6*2)+(5*1)+(4*2)+(3*8)+(2*4)+(1*5)=106
106 % 10 = 6
So 242128-45-6 is a valid CAS Registry Number.

High-yield synthesis of [2]catenanes by intramolecular ring-closing metathesis
Mohr,Weck,Sauvage,Grubbs
, p. 1308 - 1310 (2007/10/03)
Almost quantitative formation of interlocking rings results upon cyclization of threaded or intertwined complexes. The synthesis concept is based on the combination of three-dimensional template effects and ruthenium benzylidene catalyzed ring-closing met
