Check Digit Verification of cas no

The CAS Registry Mumber 1012342-23-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,2,3,4 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1012342-23:
(9*1)+(8*0)+(7*1)+(6*2)+(5*3)+(4*4)+(3*2)+(2*2)+(1*3)=72
72 % 10 = 2
So 1012342-23-2 is a valid CAS Registry Number.

Catalytic asymmetric protonation of silyl ketene imines

Guin, Joyram,Varseev, Georgy,List, Benjamin

supporting information, p. 2100 - 2103 (2013/03/28)

An efficient catalytic and highly enantioselective protonation of silyl ketene imines is described. The reaction is catalyzed by the chiral phosphoric acids TRIP or STRIP in the presence of a stoichiometric amount of methanol as the proton source and silyl acceptor. A variety of substituted racemic silyl ketene imines have been transformed into highly enantioenriched nitriles.
