Check Digit Verification of cas no
The CAS Registry Mumber 912655-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,2,6,5 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 912655-03:
(8*9)+(7*1)+(6*2)+(5*6)+(4*5)+(3*5)+(2*0)+(1*3)=159
159 % 10 = 9
So 912655-03-9 is a valid CAS Registry Number.

Synthetic studies towards (-)-lemonomycin, synthesis of fused tetracycles

The asymmetric synthesis of 1,3-lactol-bridged tetrahydroisoquinoline 5 is developed. Subsequent cyclization of 5 under acidic conditions leads to the formation of a tricyclic enamide 22, which is in turn converted to a tetracyclic compound 23. Georg Thie
