Check Digit Verification of cas no

The CAS Registry Mumber 1030702-50-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,0,7,0 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1030702-50:
(9*1)+(8*0)+(7*3)+(6*0)+(5*7)+(4*0)+(3*2)+(2*5)+(1*0)=81
81 % 10 = 1
So 1030702-50-1 is a valid CAS Registry Number.

Efficient catalysis of Ullmann-type arylation reactions by a novel trinuclear copper(I) complex with a chelating tricarbene ligand

Tubaro, Cristina,Biffis, Andrea,Scattolin, Elena,Basato, Marino

, p. 4187 - 4195 (2008)

A novel trinuclear copper(I) complex with a chelating tricarbene ligand is shown to be an efficient catalyst for the arylation of different classes of compounds containing N-H or O-H functions. Different kinds of azole rings (pyrazole, imidazole, 1,2,4-triazole) can be arylated with comparable efficiencies at relatively mild temperatures (100 °C). The catalyst activates aryl iodides, bromides and even chlorides for the reaction. An unusually strong influence of the nature of the aryl substituent on the reaction yield is observed. The synthetic protocol can be extended to other substrate classes, such as phenols and amides, although the catalytic efficiency with amides is significantly reduced.
