Check Digit Verification of cas no

The CAS Registry Mumber 346725-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,6,7,2 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 346725-03:
(8*3)+(7*4)+(6*6)+(5*7)+(4*2)+(3*5)+(2*0)+(1*3)=149
149 % 10 = 9
So 346725-03-9 is a valid CAS Registry Number.

Synthesis of substituted oxindoles from α-chloroacetanilides via palladium-catalyzed C - H functionalization

Hennessy, Edward J.,Buchwald, Stephen L.

, p. 12084 - 12085 (2007/10/03)

A novel method for the synthesis of oxindoles is described. In the presence of catalytic palladium acetate and 2-(di-tert-butylphosphino)biphenyl, α-chloroacetanilides are converted to oxindoles in good to excellent yields with high functional group compatibility using triethylamine as a stoichiometric base. The cyclization is highly regioselective, obviating the need for prefunctionalized arenes. Plausible mechanistic pathways for the reaction are discussed. Copyright
