Check Digit Verification of cas no

The CAS Registry Mumber 1239617-20-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,1 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1239617-20:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*1)+(3*7)+(2*2)+(1*0)=159
159 % 10 = 9
So 1239617-20-9 is a valid CAS Registry Number.

Silver- and gold-mediated intramolecular cyclization to substituted tetracyclic isoquinolizinium hexafluorostilbates

Liu, Fang,Ding, Xiao,Zhang, Lei,Zhou, Yu,Zhao, Linxiang,Jiang, Hualiang,Liu, Hong

experimental part, p. 5810 - 5820 (2010/10/18)

A convenient route for the synthesis of various charged tetracyclic isoquinolizinium hexafluorostilbates was developed using AgSbF 6/AuCl(PPh3) for the intramolecular addition of amine to alkyne. The described process is tolerant of a variety of functional groups and broadens the diversity of substrates with the use of 8-substituted tetracyclic isoquinolizinium salts.
