Check Digit Verification of cas no

The CAS Registry Mumber 1289031-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,0,3 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1289031-44:
(9*1)+(8*2)+(7*8)+(6*9)+(5*0)+(4*3)+(3*1)+(2*4)+(1*4)=162
162 % 10 = 2
So 1289031-44-2 is a valid CAS Registry Number.

Hydrogen bonding-directed quantitative self-assembly of cyclotriveratrylene capsules and their encapsulation of C60 and C70

Wang, Lu,Wang, Gui-Tao,Zhao, Xin,Jiang, Xi-Kui,Li, Zhan-Ting

, p. 3531 - 3535 (2011/06/22)

Under the direction of intramolecular three-center hydrogen bonding, two cyclotriveratrylene (CTV)-based capsules are assembled quantitatively from C3-symmetric CTV precursors by forming three imine bonds from arylamide-derived foldamer segments. 1H and 13C NMR and UV/vis experiments reveal that the capsules strongly encapsulate C60 and C70 in discrete solvents.
