81174-61-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81174-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,7 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81174-61:
(7*8)+(6*1)+(5*1)+(4*7)+(3*4)+(2*6)+(1*1)=120
120 % 10 = 0
So 81174-61-0 is a valid CAS Registry Number.

Synthesis of the first rotaxane containing a paracyclophane ring
Gilliatt,Sultany,Butcher Jr.
, p. 6255 - 6258 (2007/10/02)
A rotaxane, formed in ~50% yield via the standard threading procedure, exhibits profound changes in the NMR spectrum which are attributed to magnetic anisotropy caused by aromatic rings in the trityl groups and the [2.18] paracyclophane.
