Check Digit Verification of cas no

The CAS Registry Mumber 643754-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,5 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 643754-20:
(8*6)+(7*4)+(6*3)+(5*7)+(4*5)+(3*4)+(2*2)+(1*0)=165
165 % 10 = 5
So 643754-20-5 is a valid CAS Registry Number.

Switching between Novel Samarium(II)-Mediated Cyclizations by a Simple Change in Alcohol Cosolvent

Hutton, Thomas K.,Muir, Kenneth W.,Procter, David J.

, p. 4811 - 4814 (2003)

(Equation Presented) γ,δ-Unsaturated ketones undergo two very different stereoselective cyclization reactions mediated by samarium(II) iodide depending upon the alcohol cosolvent used in the reaction. Switching between an unprecedented aldol spirocyclizat
