Check Digit Verification of cas no

The CAS Registry Mumber 89393-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,9 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89393-00:
(7*8)+(6*9)+(5*3)+(4*9)+(3*3)+(2*0)+(1*0)=170
170 % 10 = 0
So 89393-00-0 is a valid CAS Registry Number.

γ-halo-enones: A method for their synthesis from arylacyl halides and their application to the preparation of five-membered ring heterocycles

A simple method has been developed for synthesis of γ-halo-enones. The approach employs a sequence involving initial indium-mediated allenylation reactions of phenacyl halides with propargyl bromide. This process is followed by acid-promoted rearrangement reactions of the formed homoallenic halohydrins. The new method can be incorporated into routes for the efficient synthesis of various five-membered heterocyclic compounds.
