Check Digit Verification of cas no

The CAS Registry Mumber 1456905-15-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,6,9,0 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1456905-15:
(9*1)+(8*4)+(7*5)+(6*6)+(5*9)+(4*0)+(3*5)+(2*1)+(1*5)=179
179 % 10 = 9
So 1456905-15-9 is a valid CAS Registry Number.

Cu-Catalyzed alkynylation-cyclization cascade for the construction of the pyrazolo[5,1-a]isoquinoline skeleton

Yang, Yanfang,Ren, Hailong,Wang, Dongyang,Shi, Feng,Wu, Chunrui

, p. 10434 - 10441 (2013)

A Cu-catalyzed Sonogashira-type coupling of 3-(2-bromophenyl)pyrazoles with terminal alkynes combined with a subsequent electrophilic cyclization in the same pot was developed to afford pyrazolo[5,1-a]isoquinolines. The transformation proceeds without the necessity of using Pd or ligands, while an Ag additive is beneficial. The Royal Society of Chemistry 2013.
