Check Digit Verification of cas no

The CAS Registry Mumber 1351685-22-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,1,6,8 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1351685-22:
(9*1)+(8*3)+(7*5)+(6*1)+(5*6)+(4*8)+(3*5)+(2*2)+(1*2)=157
157 % 10 = 7
So 1351685-22-7 is a valid CAS Registry Number.

Controlled reversible anchoring of η6-arene/TsDPEN- ruthenium(II) complex onto magnetic nanoparticles: A new strategy for catalyst separation and recycling

Wu, Lei,He, Yan-Mei,Fan, Qing-Hua

, p. 2915 - 2919 (2012/01/03)

A new catalyst separation and recycling protocol combining magnetic nanoparticles and host-guest assembly was developed. The catalyst, (η6-arene)[N-(para-toluenesulfonyl)-1,2-diphenylethylenediamine] ruthenium trifluoromethanesulfonate [Ru(OTf)(TsDPEN)(η6-arene)] bearing a dialkylammonium salt tag, was easily separated from the reaction mixtures by magnet-assisted decantation, on basis of the formation of a pseudorotaxane complex by using dibenzo[24]crown-8-modified Fe3O 4 nanoparticles. The ruthenium catalyst has been successfully reused at least 5 times with the retention of enantioselectivity but at the expense of relatively low catalytic activities in the asymmetric hydrogenation of 2-methylquinoline.
