Check Digit Verification of cas no

The CAS Registry Mumber 1374419-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,4,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1374419-22:
(9*1)+(8*3)+(7*7)+(6*4)+(5*4)+(4*1)+(3*9)+(2*2)+(1*2)=163
163 % 10 = 3
So 1374419-22-3 is a valid CAS Registry Number.

Site-selective sonogashira reactions of 1,4-dibromo-2-fluorobenzene - Synthesis and properties of fluorinated alkynylbenzenes

Reimann, Sebastian,Sharif, Muhammad,Hein, Martin,Villinger, Alexander,Wittler, Kai,Ludwig, Ralf,Langer, Peter

, p. 604 - 615 (2012/03/08)

A variety of alkynyl-substituted fluorinated benzene derivatives have been prepared by Sonogashira cross-coupling reactions of 1,4-dibromo-2-fluorobenzene. The reactions proceed with very good site-selectivity in favor of the 4-position because of electro
