Check Digit Verification of cas no

The CAS Registry Mumber 1610734-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,7,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1610734-19:
(9*1)+(8*6)+(7*1)+(6*0)+(5*7)+(4*3)+(3*4)+(2*1)+(1*9)=134
134 % 10 = 4
So 1610734-19-4 is a valid CAS Registry Number.

A general and practical palladium-catalyzed direct a-arylation of amides with aryl halides

Zheng, Bing,Jia, Tiezheng,Walsh, Patrick J.

, p. 165 - 178 (2014/03/21)

An efficient system for the direct catalytic intermolecular α-arylation of acetamide derivatives with aryl bromides and chlorides is presented. The palladium catalyst is supported by Kwong's indolebased phosphine ligand and provides monoarylated amides in up to 95% yield. Excellent chemoselectivities (>10:1) in the mono- and diarylation with aryl bromides were achieved by careful selection of bases, solvents, and stoichiometry. Under the coupling conditions, the weakly acidic α-protons of amides (pK a up to 35) were reversibly depotonated by lithium tert-butoxide (LiO-t-Bu), sodium tert-butoxide (NaO-t-Bu) or sodium bis(trimethylsilyl)amide [NaN(SiMe3)2].
