Calculate Digit Verification of CAS Registry Number 258289-41:
(8*2)+(7*5)+(6*8)+(5*2)+(4*8)+(3*9)+(2*4)+(1*1)=177
177 % 10 = 7
So 258289-41-7 is a valid CAS Registry Number.

, p. 2943 - 2952 (2007/10/03)

The total synthesis of renierone, mimocin, renierol, renierol acetate, renierol propionate, and 7-methoxy-1,6-dimethylisoquinoline-5,8-dione was successfully achieved by the regioselective oxidation of 5-oxygenated isoquinoline. The synthetic method of the 5-oxygenated isoquinoline is based on the thermal electrocyclic reaction of 1-azahexatriene system involving the benzene 1,2-bond.
