Check Digit Verification of cas no

The CAS Registry Mumber 503272-80-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,2,7 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 503272-80:
(8*5)+(7*0)+(6*3)+(5*2)+(4*7)+(3*2)+(2*8)+(1*0)=118
118 % 10 = 8
So 503272-80-8 is a valid CAS Registry Number.

Transition metal control in the reaction of alkyne-substituted phenyl iodides with terminal alkynes: Sonogashira coupling vs cyclic carbopalladation

Teply, Filip,Stará, Irena G.,Stary, Ivo,Kollárovi?, Adrian,?aman, David,Fiedler, Pavel

, p. 9007 - 9018 (2007/10/03)

Reaction between terminal alkynes and phenyl iodides bearing a tethered alkyne unit can be effectively controlled by the nature of a transition metal catalyst. Whereas the use of Pd(0)/Cu(I) promotes the expected Sonogashira coupling to give phenyl alkyne
