Check Digit Verification of cas no

The CAS Registry Mumber 1046828-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,6,8,2 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1046828-46:
(9*1)+(8*0)+(7*4)+(6*6)+(5*8)+(4*2)+(3*8)+(2*4)+(1*6)=159
159 % 10 = 9
So 1046828-46-9 is a valid CAS Registry Number.

Chiral phosphoric acid-catalyzed enantioselective aza-Friedel-Crafts reaction of indoles

Terada, Masahiro,Yokoyama, Shigeko,Sorimachi, Keiichi,Uraguchi, Daisuke

, p. 1863 - 1867 (2008/09/17)

A highly enantioselective 1,2-aza-Friedel-Crafts reaction of N-tert-butyldimethylsilylindole with N-tert-butoxycarbonyl aromatic imines is demonstrated using a BINOL-derived monophosphoric acid catalyst. The present approach provides efficient access to 3-indolylmethaneamines with aryl substituents in excellent enantioselectivities (up to 98% ee). An inversion in the sense of enantioselection was found between monophosphoric acid catalysts bearing different substituents introduced at the 3,3′-position of binaphthyl backbone. We also calculated the three-dimensional structure of the monophosphoric acid catalysts to speculate on the inversion of the stereochemical outcome.
