Check Digit Verification of cas no

The CAS Registry Mumber 192655-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,6,5 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 192655-92:
(8*1)+(7*9)+(6*2)+(5*6)+(4*5)+(3*5)+(2*9)+(1*2)=168
168 % 10 = 8
So 192655-92-8 is a valid CAS Registry Number.

Reactive dications: The superacid-catalyzed reactions of alkynes bearing adjacent N-heterocycles or amine groups

Klumpp, Douglas A.,Rendy, Rendy,Zhang, Yun,McElrea, Aaron,Gomez, Alma,Dang, Han

, p. 8108 - 8110 (2004)

A variety of aminoalkynes and related heterocycles are reacted in the Bronsted superacid CF3SO3H (triflic acid), and products are obtained in generally good yields (69-99%) from Friedel-Crafts-type reactions. The reactions are consistent with the formation of novel dicationic intermediates having a vinyl cationic site and an adjacent protonated N-heterocycle or ammonium cation.
