107428-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107428-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,4,2 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107428-39:
(8*1)+(7*0)+(6*7)+(5*4)+(4*2)+(3*8)+(2*3)+(1*9)=117
117 % 10 = 7
So 107428-39-7 is a valid CAS Registry Number.

INTERLOCKED MACROCYCLIC LIGANDS: A CATENAND WHOSE ROTATION OF ONE RING INTO THE OTHER IS PRECLUDED BY BULKY SUBSTITUENTS.
Dietrich-Buchecker, C. O.,Sauvage, J. P.,Weiss, J.
, p. 2257 - 2260 (2007/10/02)
A new highly rigid catenand has been synthesized.It contains two interlocked rings whose reciprocal motions are highly restricted, making the topography of the copper(I) catenate similar to that of the free ligand.
