87306-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87306-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,0 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87306-90:
(7*8)+(6*7)+(5*3)+(4*0)+(3*6)+(2*9)+(1*0)=149
149 % 10 = 9
So 87306-90-9 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.
