Check Digit Verification of cas no

The CAS Registry Mumber 171182-88-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,1,8 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 171182-88:
(8*1)+(7*7)+(6*1)+(5*1)+(4*8)+(3*2)+(2*8)+(1*8)=130
130 % 10 = 0
So 171182-88-0 is a valid CAS Registry Number.

Tris[(1H,1H,2H,2H-perfluoroalkyl) aryl]phoshites and catalytic uses thereof

-

, (2008/06/13)

A method for preparing tris[(1H,1H,2H,2H-perfluoroalkyl)aryl]phosphites consists in preparing a grignard reagent from an alkoxyhalogenobenzene, then reacting it with a iodo-1H,1H,2H,2H-perfluoroalkane; transforming the alkoxy function of (1H,1H,2H,2H,2H-perfluoroalkyl)alkoxybenzene obtained into a hydroxy function, then reacting (1H,1H,2H,2H-perfluoroalkyl)hydroxybenzene with PCl3. The invention also concerns fluorinated arylphosphites and their use as transition metal ligand for making catalysts to be used in two-phase catalysis with fluorinated phase.
