Check Digit Verification of cas no

The CAS Registry Mumber 120665-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,6 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120665-69:
(8*1)+(7*2)+(6*0)+(5*6)+(4*6)+(3*5)+(2*6)+(1*9)=112
112 % 10 = 2
So 120665-69-2 is a valid CAS Registry Number.

Synthesis of (+)-Taxodione

Haslinger, Ernst,Michl, Guenter

, p. 677 - 686 (2007/10/02)

A stereoselective synthesis of (+)-taxodione (1) starting from (-)-abietic acid (2) via the ironcarbonyl complex 4 is described.Conversion of the carboxyl function of 4 into a methyl group via 5 and 6 proceeds in excellent overall yield.The next steps are the introduction of oxygen functions in the positions 12 and 6.Oxidation with BSA yields the quinonemethide 1.The 1H- and 13C-NMR resonances of all compounds have been assigned.
