Check Digit Verification of cas no

The CAS Registry Mumber 1385067-45-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,5,0,6 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1385067-45:
(9*1)+(8*3)+(7*8)+(6*5)+(5*0)+(4*6)+(3*7)+(2*4)+(1*5)=177
177 % 10 = 7
So 1385067-45-7 is a valid CAS Registry Number.

New domino heteroannulation of enaminones: Synthesis of diverse fused naphthyridines

Li, Jing,Yu, Yan,Tu, Man-Su,Jiang, Bo,Wang, Shu-Liang,Tu, Shu-Jiang

experimental part, p. 5361 - 5365 (2012/08/07)

A series of new poly-functionalized fused naphthyridine derivatives were synthesized via a three-component reaction of aldehyde, 2-aminoprop-1-ene-1,1,3- tricarbonitrile and enaminone in EtOH using EtONa as a base. During these reaction processes, the domino construction of fused naphthyridine skeleton with concomitant formation of two new pyridine rings was readily achieved via base promoted three-component reactions in a one-pot operation. The procedures are facile, avoiding time-consuming and costly syntheses, tedious work-up and purifications of precursors.
