94235-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94235-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,3 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94235-71:
(7*9)+(6*4)+(5*2)+(4*3)+(3*5)+(2*7)+(1*1)=139
139 % 10 = 9
So 94235-71-9 is a valid CAS Registry Number.

Enantioselective Synthesis of 2,2',6-Trisubstituted Biphenyls
Meyers, A. I.,Himmelsbach, Richard J.
, p. 682 - 685 (2007/10/02)
A general procedure is described for the synthesis of chiral biphenyls via nucleophilic aromatic substitution of an o-methoxy group by an aryl Grignard reagent with an oxazoline as a chiral auxiliary.
