Check Digit Verification of cas no

The CAS Registry Mumber 1045346-58-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,3,4 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1045346-58:
(9*1)+(8*0)+(7*4)+(6*5)+(5*3)+(4*4)+(3*6)+(2*5)+(1*8)=134
134 % 10 = 4
So 1045346-58-4 is a valid CAS Registry Number.

Gold(III) chloride-catalyzed three-component reaction: A facile synthesis of alkynyl derivatives of 1,2-dihydroquinolines and isoquinolines

Yadav, Jhillu S.,Subba Reddy, Basi V.,Yadav, Nagendra Nath,Gupta, Manoj K.,Sridhar, Balasubramanian

, p. 6857 - 6859 (2008)

(Chemical Equation Presented) Gold(III) chloride is found to be an effective catalyst for the addition of alkynes on activated quinoline/ isoquinolines to produce a series of alkynyl-substituted 1,2-dihydroquinolines and isoquinolines in a single-step operation. The easy availability of starting materials, convenient synthetic procedure, operational simplicity, and high regioselectivity makes this strategy very useful for the preparation of enyne derivatives of aza-aromatic compounds.
