Check Digit Verification of cas no
The CAS Registry Mumber 5439-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,3 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5439-04:
(6*5)+(5*4)+(4*3)+(3*9)+(2*0)+(1*4)=93
93 % 10 = 3
So 5439-04-3 is a valid CAS Registry Number.

Palladium-catalyzed carbonylation of polychlorinated pyridines. A simple laboratory approach to metal catalyzed carbonylation reactions
Hull Jr., John W.,Wang, Chen
, p. 411 - 417 (2007/10/03)
The palladium-catalyzed carbonylation reactions of pentachloropyridine and 2,3,4,5-tetrachloropyridine were investigated in alcoholic or aqueous solvent. The high boiling alcohol 2-ethyl-1-hexanol was an effective carbonylation solvent above 100 °C at 1 atm of CO, representing a convenient and simple method for carrying out transition metal catalyzed carbonylation reactions using standard laboratory glassware.
