89901-00-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89901-00-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,0 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89901-00:
(7*8)+(6*9)+(5*9)+(4*0)+(3*1)+(2*0)+(1*0)=158
158 % 10 = 8
So 89901-00-8 is a valid CAS Registry Number.

Efficient cobalt-catalyzed formation of unsymmetrical biaryl compounds and its application in the synthesis of a sartan intermediate

Amatore, Muriel,Gosmini, Corinne

supporting information; experimental part, p. 2089 - 2092 (2009/02/06)

(Chemical Equation Presented) No prior preparation of the organometallic reagent is required in a cobalt-catalyzed coupling of two different aryl halides under mild conditions (see scheme). A broad spectrum of valuable biaryl compounds can be prepared in this way. Not only may a variety of reactive substituents be present, but heteroaryl halides and aryl triflates are also suitable substrates. DMF = N,N-dimethylformamide, FG = functional group.
