Check Digit Verification of cas no

The CAS Registry Mumber 1239498-96-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,4,9 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1239498-96:
(9*1)+(8*2)+(7*3)+(6*9)+(5*4)+(4*9)+(3*8)+(2*9)+(1*6)=204
204 % 10 = 4
So 1239498-96-4 is a valid CAS Registry Number.

Total synthesis of bafilomycin A1

Kleinbeck, Florian,Fettes, Gabriela J.,Fader, Lee D.,Carreira, Erick M.

, p. 3598 - 3610 (2012/05/04)

A convergent synthesis of bafilomycin A1, a potent inhibitor of V-type ATPases, is presented. The synthesis relies on the zinc triflate mediated diastereoselective addition of a complex enyne to a sensitive aldehyde as the key fragment coupling. A ruthenium-catalyzed trans-reduction of the resulting propargylic enyne efficiently installs the required C10-C13 trans,trans-diene subunit, implementing an alternative strategy to traditional palladium-catalyzed cross-coupling strategies. A highly selective oxidation of a secondary hydroxyl group in a triol sets the stage for the completion of the synthesis. Copyright
