Check Digit Verification of cas no

The CAS Registry Mumber 1291080-09-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,8 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1291080-09:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*8)+(3*0)+(2*0)+(1*9)=135
135 % 10 = 5
So 1291080-09-5 is a valid CAS Registry Number.

Synthesis of 3-Iodoquinolines by Copper-Catalyzed Tandem Annulation from Diaryliodoniums, Nitriles, and 1-Iodoalkynes

Wang, Xuesong,Wang, Xingyong,Huang, Dayun,Liu, Chulong,Wang, Xinyan,Hu, Yuefei

, p. 2332 - 2339 (2016/07/28)

A novel method for the synthesis of 3-iodoquinolines was developed by copper-catalyzed tandem annulation from diaryliodoniums, nitriles, and 1-iodoalkynes. It is a method that is characterized by the most convenient operation and wide molecular diversity. (Figure presented.) .
