Check Digit Verification of cas no

The CAS Registry Mumber 27930-14-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,3 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27930-14:
(7*2)+(6*7)+(5*9)+(4*3)+(3*0)+(2*1)+(1*4)=119
119 % 10 = 9
So 27930-14-9 is a valid CAS Registry Number.

An atom economical method for the direct synthesis of quinoline derivatives from substituted o-nitrotoluenes

Liu, Guiyan,Yi, Maocong,Liu, Lu,Wang, Jingjing,Wang, Jianhui

, p. 2911 - 2914 (2015)

A highly efficient one-pot procedure for the preparation of substituted quinolines from substituted o-nitrotoluenes with electron-withdrawing groups and olefins (acrylic esters and acrylonitriles) using a cesium catalyst has been developed. A plausible [2+4] cycloaddition mechanism is proposed. This method uses nitroaromatic compounds as the starting materials to give quinoline derivatives in good to high yields under mild conditions with no transition metal catalysis. It provides an atom economical pathway for the synthesis of quinoline derivatives which could be used in industrial processes.
