Check Digit Verification of cas no

The CAS Registry Mumber 1132970-10-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,9,7 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1132970-10:
(9*1)+(8*1)+(7*3)+(6*2)+(5*9)+(4*7)+(3*0)+(2*1)+(1*0)=125
125 % 10 = 5
So 1132970-10-5 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
