Check Digit Verification of cas no

The CAS Registry Mumber 1217436-70-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,4,3 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1217436-70:
(9*1)+(8*2)+(7*1)+(6*7)+(5*4)+(4*3)+(3*6)+(2*7)+(1*0)=138
138 % 10 = 8
So 1217436-70-8 is a valid CAS Registry Number.

Synthesis of substituted quinolines by the electrophilic cyclization of n-(2-alkynyl)anilines

Zhang, Xiaoxia,Yao, Tuanli,Campo, Marino A.,Larock, Richard C.

supporting information; experimental part, p. 1177 - 1187 (2010/04/02)

A wide variety of substituted quinolines are readily synthesized under mild reaction conditions by the 6-endo-dig electrophilic cyclization of N-(2-alkynyl)anilines by ICl, I2, Br2, PhSeBr, and p-O2NC6H4SCl. The reaction affords 3-halogen-, selenium- and sulfur-containing quinolines in moderate to good yields in the presence of various functional groups. Analogous quinolines bearing a hydrogen in the 3-position have been synthesized by the Hg(OTf)2-catalyzed ring closure of these same alkynylanilines.
