102757-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102757-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,5 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 102757-87:
(8*1)+(7*0)+(6*2)+(5*7)+(4*5)+(3*7)+(2*8)+(1*7)=119
119 % 10 = 9
So 102757-87-9 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.
