181288-08-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 181288-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,8 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 181288-08:
(8*1)+(7*8)+(6*1)+(5*2)+(4*8)+(3*8)+(2*0)+(1*8)=144
144 % 10 = 4
So 181288-08-4 is a valid CAS Registry Number.

Nickel-catalyzed Negishi cross-coupling reactions of secondary alkylzinc halides and aryl iodides

Joshi-Pangu, Amruta,Ganesh, Madhu,Biscoe, Mark R.

supporting information; experimental part, p. 1218 - 1221 (2011/04/27)

A general Ni-catalyzed process for the cross-coupling of secondary alkylzinc halides and aryl/heteroaryl iodides has been developed. This is the first process to overcome the isomerization and β-hydride elimination problems that are associated with the use of secondary nucleophiles, and that have limited the analogous Pd-catalyzed systems. The impact of salt additives was also investigated. It was found that the presence of LiBF4 dramatically improves both isomeric retention and yield for challenging substrates.(Figure Presented)

9-(P-phenylazoanilino)-7-methyl-1H-imidazo[4,5-f]quinolines
