Calculate Digit Verification of CAS Registry Number 960069-40:
(8*9)+(7*6)+(6*0)+(5*0)+(4*6)+(3*9)+(2*4)+(1*0)=173
173 % 10 = 3
So 960069-40-3 is a valid CAS Registry Number.

(tmp)2Zn·2 MgCl2·2 LiCl: A chemoselective base for the directed zincation of sensitive arenes and heteroarenes

Wunderlich, Stefan H.,Knochel, Paul

, p. 7685 - 7688 (2008/09/18)

(Chemical Equation Presented) Positive zincing: A wide range of polyfunctional aryl and heteroaryl zinc reagents were efficiently prepared in THF by direct zincation using (tmp)2Zn·2 MgCl 2·2 LiCl (1), an exceptionally active base. Ester and cyano functions as well as aldehydes and nitro groups are tolerated. dba = dibenzylideneacetone, tmp = 2,2,6,6-tetramethylpiperidide.
