Calculate Digit Verification of CAS Registry Number 1309458-30:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*5)+(3*8)+(2*3)+(1*0)=157
157 % 10 = 7
So 1309458-30-7 is a valid CAS Registry Number.

A boron-based synthesis of the natural product (+)-trans- dihydrolycoricidine

Poe, Sarah L.,Morken, James P.

, p. 4189 - 4192 (2011/06/20)

Diastereoselective diboration results in the highly selective 1,4-dihydroxylation of chiral cyclohexadienes (see scheme). Together with the catalytic enantioselective conjugate allylboration, the diene diboration facilitates the asymmetric synthesis of the cytotoxic agent (+)-trans- dihydrolycoricidine (1). pin=pinacol.
