The CAS Registry Mumber 194418-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,1 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 194418-48:
(8*1)+(7*9)+(6*4)+(5*4)+(4*1)+(3*8)+(2*4)+(1*8)=159
159 % 10 = 9
So 194418-48-9 is a valid CAS Registry Number.

A new regio- and stereoselective intermolecular Friedel-Crafts alkylation of phenolic substrates with aryl epoxides

Bertolini, Ferruccio,Crotti, Paolo,Macchia, Franco,Pineschi, Mauro

, p. 61 - 64 (2007/10/03)

A conceptually new regioselective and highly syn-stereoselective intermolecular Friedel-Crafts-type O-alkylation of phenols with aryl epoxides by the use of appropriately substituted aryl borates is reported. The carbon-carbon bond formation occurs in neutral and mild conditions without the need for external Lewis acids or transition metal catalysts.
