Check Digit Verification of cas no
The CAS Registry Mumber 22040-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,4 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 22040-08:
(7*2)+(6*2)+(5*0)+(4*4)+(3*0)+(2*0)+(1*8)=50
50 % 10 = 0
So 22040-08-0 is a valid CAS Registry Number.

Substitution of hydroxybiaryls via directed ortho-lithiation of N-silylated O-aryl N-isopropylcarbamates
Kauch, Matthias,Snieckus, Victor,Hoppe, Dieter
, p. 7149 - 7158 (2007/10/03)
Herein we report regioselective substitution reactions of a series of 2- and 3-hydroxybiaryls including BINOL via a new directed ortho-metalation procedure. O-Aryl N-isopropylcarbamates, conveniently prepared from phenols and isopropyl isocyanate, are tem
