Check Digit Verification of cas no

The CAS Registry Mumber 1621621-95-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,6,2 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1621621-95:
(9*1)+(8*6)+(7*2)+(6*1)+(5*6)+(4*2)+(3*1)+(2*9)+(1*5)=141
141 % 10 = 1
So 1621621-95-1 is a valid CAS Registry Number.

Directed C-H alkenylation of quinoline N-oxides at the C-8 position using a cationic rhodium(I) catalyst

Shibata, Takanori,Matsuo, Yusuke

supporting information, p. 1516 - 1520 (2014/06/09)

The cationic rhodium-catalyzed alkenylation proceeds at the C-8 position of quinoline N-oxides. Regioselective C-H bond activation was achieved by the directing effect of the anionic oxygen of an N-oxide moiety, which can be readily removed by reductive treatment. A variety of 8-alkenylated quinoline N-oxides was obtained in moderate to high yields.
