Check Digit Verification of cas no

The CAS Registry Mumber 29686-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,8 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29686-21:
(7*2)+(6*9)+(5*6)+(4*8)+(3*6)+(2*2)+(1*1)=153
153 % 10 = 3
So 29686-21-3 is a valid CAS Registry Number.

Hydrogen activation by 2-boryl-N,N-dialkylanilines: A revision of Piers' ansa-aminoborane

Chernichenko, Konstantin,Nieger, Martin,Leskelae, Markku,Repo, Timo

supporting information; body text, p. 9029 - 9032 (2012/09/08)

Two 2-[bis(pentafluorophenyl)boryl]-N,N-dialkylanilines reported here exemplify a new class of intramolecular frustrated B/N Lewis pairs. A structure closely related to this class structure was synthesized in 2003 by Piers et al. but was unable to activate H2. The new aminoboranes can activate hydrogen at near ambient conditions; besides, one of them can hydrogenate imines and enamines in a catalytic fashion demonstrating the validity of the original Piers' approach to hydrogen activation with ansa-aminoboranes.
