1072448-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1072448-46-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,2,4,4 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1072448-46:
(9*1)+(8*0)+(7*7)+(6*2)+(5*4)+(4*4)+(3*8)+(2*4)+(1*6)=144
144 % 10 = 4
So 1072448-46-4 is a valid CAS Registry Number.

Palladium- and nickel-catalyzed cross-couplings of unsaturated halides bearing relatively acidic protons with organozinc reagents

Manolikakes, Georg,Munoz Hernandez, Carmen,Schade, Matthias A.,Metzger, Albrecht,Knochel, Paul

supporting information; experimental part, p. 8422 - 8436 (2009/04/11)

(Chemical Equation Presented) A wide range of polyfunctional aryl, heteroaryl, alkyl, and benzylic zinc reagents were coupled with unsaturated aryl halides bearing an acidic NH or OH proton, using Pd(OAc)2 (1 mol %) and S-Phos (2 mol %) as catalyst without the need of protecting groups. A similar nickel-catalyzed reaction is described. The relative kinetic basicity of organozinc compounds as well as their stability toward acidic protons is also described.
