Check Digit Verification of cas no

The CAS Registry Mumber 1290117-78-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,1,1 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1290117-78:
(9*1)+(8*2)+(7*9)+(6*0)+(5*1)+(4*1)+(3*7)+(2*7)+(1*8)=140
140 % 10 = 0
So 1290117-78-0 is a valid CAS Registry Number.

Sonogashira reaction on pyridinium N-heteroarylaminides

Córdoba, Marta,Izquierdo, M. Luisa,Alvarez-Builla, Julio

, p. 1738 - 1741 (2011)

The reactivity of N-(5-iodopyridin-2-yl)aminide in a copper-free Sonogashira cross-coupling process is reported. The reaction proceeds on using PdCl2(PPh3)2 and DABCO as the base under microwave irradiation in acetonitrile or water as solvents. The process can also be carried out by traditional heating in acetonitrile on using Pd(AcO) 2/DABCO with Cs2CO3.
