Check Digit Verification of cas no

The CAS Registry Mumber 16206-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16206-67:
(7*1)+(6*6)+(5*2)+(4*0)+(3*6)+(2*6)+(1*7)=90
90 % 10 = 0
So 16206-67-0 is a valid CAS Registry Number.

A total synthesis of (±)-codeine by 1,3-dipolar cycloaddition

Erhard, Thomas,Ehrlich, Gunnar,Metz, Peter

, p. 3892 - 3894 (2011/06/24)

Nitrone cycloaddition on a dearomatized bicyclic phenol enabled the facile construction of the correctly configured phenanthrene skeleton of codeine. Further steps yielded allopseudocodeine in a completely diastereoselective manner and finally (±)-codeine by allylic transposition through the hydrolysis of chlorocodides.
