Check Digit Verification of cas no

The CAS Registry Mumber 1260216-06-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,2,1 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1260216-06:
(9*1)+(8*2)+(7*6)+(6*0)+(5*2)+(4*1)+(3*6)+(2*0)+(1*6)=105
105 % 10 = 5
So 1260216-06-5 is a valid CAS Registry Number.

Synthesis of tylocrebrine and related phenanthroindolizidines by VOF 3-mediated oxidative aryl-alkene coupling

Niphakis, Micah J.,Georg, Gunda I.

, p. 196 - 199 (2011/03/19)

A highly convergent strategy to prepare phenanthroindolizidines is reported involving three consecutive C-C coupling reactions. This sequence features a novel VOF3-mediated aryl-alkene coupling in the final step, which enables regioselective preparation of C5-substituted phenanthroindolizidines for the first time. This strategy has been applied to the synthesis of eight natural and unnatural members in this class to investigate the scope of this chemistry and to explore structure-activity relationships.
