Check Digit Verification of cas no

The CAS Registry Mumber 1402551-70-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,5,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1402551-70:
(9*1)+(8*4)+(7*0)+(6*2)+(5*5)+(4*5)+(3*1)+(2*7)+(1*0)=115
115 % 10 = 5
So 1402551-70-5 is a valid CAS Registry Number.

Synthesis of copper(I) thiolate complexes in the thioetherification of aryl halides

Chen, Chaohuang,Weng, Zhiqiang,Hartwig, John F.

, p. 8031 - 8037 (2013/01/16)

The copper(I) thiophenolato complexes 1-3 containing 1,10-phenanthroline (phen) and 2,9-dimethyl-1,10-phenanthroline (Me2phen) were isolated in excellent yields from reactions of [CuOtBu]4 with the dative ligands and subsequent addition of 1 equiv of arenethiol. These complexes were characterized spectroscopically and crystallographically. X-ray structural analysis of a single crystal of [(phen)Cu(μ-SC6H 5)]2 (1) revealed that this complex adopts a neutral dimeric form with a weak Cu-Cu bonding interaction. These complexes were found to react with iodoarenes to form aryl sulfide products. The intermediacy of such complexes in copper-catalyzed thioetherification of aryl halides was demonstrated by the reactivity with p-tolyl iodide and o-tolyl iodide to form two aryl thioethers with selectivities similar to those of catalytic reactions conducted with the same two iodoarenes.
