Check Digit Verification of cas no

The CAS Registry Mumber 64520-25-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,2 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 64520-25:
(7*6)+(6*4)+(5*5)+(4*2)+(3*0)+(2*2)+(1*5)=108
108 % 10 = 8
So 64520-25-8 is a valid CAS Registry Number.

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

Erhard, Thomas,Ehrlich, Gunnar,Metz, Peter

supporting information; experimental part, 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.

On the analysis and the stability of codeine phosphate. Part 1: Detection and determination of codeine in the presence of degradation products
