330-59-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 330-59-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 330-59:
(5*3)+(4*3)+(3*0)+(2*5)+(1*9)=46
46 % 10 = 6
So 330-59-6 is a valid CAS Registry Number.

Use of a "catalytic" Cosolvent, N,N-Dimethyl Octanamide, Allows the Flow Synthesis of Imatinib with no Solvent Switch

Yang, Jeffrey C.,Niu, Dawen,Karsten, Bram P.,Lima, Fabio,Buchwald, Stephen L.

, p. 2531 - 2535 (2016)

A general, efficient method for C-N cross-coupling has been developed using N,N-dimethyloctanamide as a catalytic cosolvent for biphasic continuous-flow applications. The described method was used to generate a variety of biarylamines and was integrated into a two-step sequence which converted phenols into biarylamines via either triflates or tosylates. Additionally, the method was applied to a three-step synthesis of imatinib, the API of Gleevec, in good yield without the need of solvent switches. Going with the flow: A general flow method developed for C-N cross-coupling using N,N-dimethyloctanamide as a catalytic cosolvent was integrated into a two-step sequence which converted phenols into biarylamines via either triflates or tosylates.
