Check Digit Verification of cas no

The CAS Registry Mumber 690629-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,6,2 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 690629-64:
(8*6)+(7*9)+(6*0)+(5*6)+(4*2)+(3*9)+(2*6)+(1*4)=192
192 % 10 = 2
So 690629-64-2 is a valid CAS Registry Number.

Titanium-mediated cross-coupling reactions of imines with ketones or aldehydes: An efficient route for the synthesis of 1,2-amino alcohols

Fan, Guoqin,Liu, Yuanhong

, p. 5084 - 5087 (2012)

The cross-coupling reactions of imines with ketones using Ti(O iPr)4/c-C5H9MgCl reagent lead to 1,2-amino alcohols after hydrolysis. The coupling reactions with aldehydes could also afford 1,2-amino alcohols, however, in some cases, aziridines were obtained as major products in a stereoselective manner.
