Check Digit Verification of cas no

The CAS Registry Mumber 39149-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,4 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39149-69:
(7*3)+(6*9)+(5*1)+(4*4)+(3*9)+(2*6)+(1*9)=144
144 % 10 = 4
So 39149-69-4 is a valid CAS Registry Number.

Solvent-dependent chemoselectivities in additions of β-carbonyl imines to allyltrimethylsilane with CTAN

Zhang, Yang,Raines, Andrew J.,Flowers II, Robert A.

, p. 6267 - 6272 (2004)

The oxidative coupling of β-carbonyl imines and allyltrimethylsilane with CTAN were investigated in CH3CN and CH2Cl 2. In CH3CN allylation products were obtained predominantly, while in CH2Cl2, dihydropyrrole products were obtained exclusively. Solvent-assisted nucleophilic cleavage of the intermediate β-silyl cation is proposed to play a role in the solvent-dependent chemoselectivity.
