Check Digit Verification of cas no
The CAS Registry Mumber 19491-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19491-17:
(7*1)+(6*9)+(5*4)+(4*9)+(3*1)+(2*1)+(1*7)=129
129 % 10 = 9
So 19491-17-9 is a valid CAS Registry Number.

Regioselective Halogenation and Dimerization of Alkoxynaphathalenes with Alumina- or Kieselguhr-supported Copper(II) Halides
Suzuki, Yoshitada,Takeuchi, Kiyoshi,Kodomari, Mitsuo
, p. 426 - 427 (2007/10/03)
The reaction of 1-alkoxynaphathalenes 1 with alumina-supported copper(II) bromide or copper(II) chloride gave dimers, 4,4'-dialkoxy-1,1'-binaphthyls 3, as major products, and with Kieselguhr-supported copper(II) bromide afforded 1-bromo-4-alkoxynaphthalenes 2, while the reaction of 2-alkoxynaphathalenes 4 with alumina- or Kieselguhr-supported copper(II) bromide gave preferentially 1-bromo-2-alkoxynaphthalenes 5.
