Check Digit Verification of cas no

The CAS Registry Mumber 199918-24-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,9,1 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 199918-24:
(8*1)+(7*9)+(6*9)+(5*9)+(4*1)+(3*8)+(2*2)+(1*4)=206
206 % 10 = 6
So 199918-24-6 is a valid CAS Registry Number.

Nickel-catalyzed heterocycle construction with stereoselective exocyclic alkene introduction

Montgomery, John,Chevliakov, Maxim V.,Brielmann, Harry L.

, p. 16449 - 16462 (2007/10/03)

A series of monocyclic and bicyclic heterocycles with exocyclic alkenes were constructed in a stereoselective fashion by an organozinc/Ni(COD)2 - mediated cyclization of alkynyl enones. Both reductive and alkylative cyclization manifolds were accessible depending on the ligand and organozinc structure. Alkylative cyclizations were generally more efficient than reductive cyclizations, particularly with cyclic substrates.
