Check Digit Verification of cas no
The CAS Registry Mumber 2665-12-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,6 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2665-12:
(6*2)+(5*6)+(4*6)+(3*5)+(2*1)+(1*2)=85
85 % 10 = 5
So 2665-12-5 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.
