Check Digit Verification of cas no

The CAS Registry Mumber 70127-97-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,2 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70127-97:
(7*7)+(6*0)+(5*1)+(4*2)+(3*7)+(2*9)+(1*7)=108
108 % 10 = 8
So 70127-97-8 is a valid CAS Registry Number.

Bronsted acid-catalyzed enantioselective Friedlaender condensations: Achiral amine promoter plays crucial role in the stereocontrol

Ren, Lei,Lei, Tao,Gong, Liu-Zhu

supporting information; experimental part, p. 11683 - 11685 (2011/12/02)

A highly enantioselective Friedlaender condensation has been established by using chiral Bronsted acids in combination with achiral amines to give quinolines in high yields (up to 99%) and with excellent enantioselectivities (up to 95%).
