934990-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 934990-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,9,9 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 934990-97:
(8*9)+(7*3)+(6*4)+(5*9)+(4*9)+(3*0)+(2*9)+(1*7)=223
223 % 10 = 3
So 934990-97-3 is a valid CAS Registry Number.

Concave pyridines for bifunctional acid-base catalysis
Liebig, Timo,Abbass, Michael,Luening, Ulrich
, p. 972 - 980 (2008/02/13)
Two bifunctional concave acid-base catalysts, 1 and 2, have been synthesized starting from 2,6-dibromopyridine (9) and 2,6-bis(ω- alkenyloxy)phenylboronic acids 8 and 10 which end up as bridgeheads in final bimacrocycles 1 and 2. One bridgehead contained
