Check Digit Verification of cas no

The CAS Registry Mumber 68913-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,1 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68913-18:
(7*6)+(6*8)+(5*9)+(4*1)+(3*3)+(2*1)+(1*8)=158
158 % 10 = 8
So 68913-18-8 is a valid CAS Registry Number.

[(NHC)Au1]-catalyzed rearrangement of allylic acetates

Marion, Nicolas,Gealageas, Ronan,Nolan, Steven P.

, p. 2653 - 2656 (2008/02/09)

Equation Presented [(NHC)AuCl] complexes (NHC = N-heterocyclic carbene), in conjunction with a silver salt, were found to efficiently catalyze the rearrangement of allylic acetates under both conventional and microwave-assisted heating. The optimization of several reaction parameters (solvent, silver salt, and ligand) as well as a study of the reaction scope are reported. The steric hindrance of the ligand bound to gold was found crucial for the outcome of the reaction as only extremely bulky ligands permitted the isomerization.
