Check Digit Verification of cas no

The CAS Registry Mumber 106874-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,8,7 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 106874-92:
(8*1)+(7*0)+(6*6)+(5*8)+(4*7)+(3*4)+(2*9)+(1*2)=144
144 % 10 = 4
So 106874-92-4 is a valid CAS Registry Number.

A NEW SYNTHESIS OF 4-AMINO-2-QUINOLINONES

Bergman, Jan,Brynolf, Anna,Vuorinen, Eino

, p. 3689 - 3696 (2007/10/02)

Addition of Grignard or organolithium reagents to N-(α-haloacyl)-N-alkylsubstituted anthranilonitriles (e.g.N-(2-bromopropionyl)-N-methyl-2-cyanoaniline)induced anion formation followed by cyclization to 4-amino-2-quinolinones (e.g. 4-amino-1,3-dimethyl-2-quinolinone (10)).Substrates lacking α-hydrogen atoms, such as N-α-bromoisobutyryl)-2-cyanoaniline, also yielded 3,3-dimethylquinolinedione (9b) by cyclization.In these cases the initial step is a halogen-metal exchange reaction.
