857579-15-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857579-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,7 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 857579-15:
(8*8)+(7*5)+(6*7)+(5*5)+(4*7)+(3*9)+(2*1)+(1*5)=228
228 % 10 = 8
So 857579-15-8 is a valid CAS Registry Number.

Nickel-catalyzed Kumada cross-coupling reactions of tertiary alkylmagnesium halides and aryl bromides/triflates

Joshi-Pangu, Amruta,Wang, Chao-Yuan,Biscoe, Mark R.

supporting information; experimental part, p. 8478 - 8481 (2011/06/25)

We report a Ni-catalyzed process for the cross-coupling of tertiary alkyl nucleophiles and aryl bromides. This process is extremely general for a wide range of electrophiles and generally occurs with a ratio of retention to isomerization >30:1. The same procedure also accommodates the use of aryl triflates, vinyl chlorides, and vinyl bromides as the electrophilic component.
