Check Digit Verification of cas no

The CAS Registry Mumber 1048338-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,8,3,3 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1048338-31:
(9*1)+(8*0)+(7*4)+(6*8)+(5*3)+(4*3)+(3*8)+(2*3)+(1*1)=143
143 % 10 = 3
So 1048338-31-3 is a valid CAS Registry Number.

Simple microwave-assisted ligand-free Suzuki cross-coupling: Functionalization of halo-pyrimidine moieties

Colombo, Matteo,Giglio, Marco,Peretto, Ilaria

, p. 1077 - 1081 (2008)

(Chemical Equation Presented) An advantageous ligand-free protocol for Suzuki couplings is described. The synthetic procedure entails microwave irradiation for the reduction of the reaction times and the use of silica cartridges for the purification. Dihalo-pyrimidine structures, interesting scaffolds in medicinal chemistry, were chosen as test compounds.
