Check Digit Verification of cas no
The CAS Registry Mumber 66115-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,1 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66115-57:
(7*6)+(6*6)+(5*1)+(4*1)+(3*5)+(2*5)+(1*7)=119
119 % 10 = 9
So 66115-57-9 is a valid CAS Registry Number.

Catalytic asymmetric bromine-lithium exchange: A new tool to build axial chirality
Perron, Quentin,Alexakis, Alexandre
supporting information; experimental part, p. 2611 - 2620 (2011/01/05)
We present here the first catalytic desymmetrization of the 2,2′,6,6′-tetrabromobiphenyl 1 and analogues, by a bromine-lithium exchange catalyzed by either diamines or diether derivatives (0.5 equiv.), yielding axially chiral compounds in high yield (up to 89%) and high enantioselectivity (up to 82%).
