Check Digit Verification of cas no

The CAS Registry Mumber 1174222-59-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,2,2 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1174222-59:
(9*1)+(8*1)+(7*7)+(6*4)+(5*2)+(4*2)+(3*2)+(2*5)+(1*9)=133
133 % 10 = 3
So 1174222-59-3 is a valid CAS Registry Number.

Carbon-carbon bond formations at the benzylic positions of N-benzylxanthone imines and N-benzyldi-1-naphthyl ketone imine

Niwa, Takashi,Suehiro, Takafumi,Yorimitsu, Hideki,Oshima, Koichiro

experimental part, p. 5125 - 5131 (2009/11/30)

Two N-benzyl imines are designed to allow for carbon-carbon bond formations at the aminated benzylic positions. Direct benzylic arylation reactions of N-benzylxanthone imine with aryl chlorides proceed under palladium catalysis in the presence of cesium hydroxide, yielding the corresponding benzhydrylamine derivatives. Alkylation reactions of N-benzyldi-1-naphthyl ketone imine with alkyl halides in the presence of potassium tert-butoxide afford the corresponding 1-phenylalkylamines in high yields. Conjugate addition of N-benzyldi-1-naphthyl ketone imine is also described.
