Check Digit Verification of cas no

The CAS Registry Mumber 1391031-42-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,0,3 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1391031-42:
(9*1)+(8*3)+(7*9)+(6*1)+(5*0)+(4*3)+(3*1)+(2*4)+(1*2)=127
127 % 10 = 7
So 1391031-42-7 is a valid CAS Registry Number.

One-pot method for α-phenylation of ketones using isoxazolidine and triphenylaluminum

Miyoshi, Tetsuya,Sato, Shohei,Tanaka, Hiroya,Hasegawa, Chihiro,Ueda, Masafumi,Miyata, Okiko

experimental part, p. 4188 - 4191 (2012/08/28)

The efficient one-pot umpolung α-phenylation of ketones via N-alkenylisoxazolidine is described. When the various ketones are treated with triphenylaluminum prepared from phenylmagnesium chloride and AlCl3 in the presence of isoxazolidine, the desired products are obtained in good to moderate yield. This method is equivalent to a direct α-arylation reaction of carbonyl groups.
