Calculate Digit Verification of CAS Registry Number 288395-79:
(8*2)+(7*8)+(6*8)+(5*3)+(4*9)+(3*5)+(2*7)+(1*9)=209
209 % 10 = 9
So 288395-79-9 is a valid CAS Registry Number.

Studies on the narciclasine alkaloids: Total synthesis of (+)- narciclasine and (+)-pancratistatin

Rigby, James H.,Maharoof, Umar S. M.,Mateo, Mary E.

, p. 6624 - 6628 (2007/10/03)

Enantioselective total syntheses of the antimmor alkaloids, (+)- narciclasine and (+)-pancratistatin, are reported. These syntheses feature a stereo- and regiocontrolled aryl enamide photocyclization to construct a common, advanced intermediate possessing a transfused BC substructure. Differential functional group interchange in the C-ring of this phenanthridone core structure allows for the production of the two target natural products in enantiomerically pure form.
