Check Digit Verification of cas no

The CAS Registry Mumber 329003-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,9,0,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 329003-67:
(8*3)+(7*2)+(6*9)+(5*0)+(4*0)+(3*3)+(2*6)+(1*7)=120
120 % 10 = 0
So 329003-67-0 is a valid CAS Registry Number.

Enantioselective catalytic cyclopropanation of styrenes by copper complexes with chiral pinene-[5,6]-bipyridine ligands

Loetscher, Didier,Rupprecht, Stefan,Stoeckli-Evans, Helen,Von Zelewsky, Alex

, p. 4341 - 4357 (2000)

Substituted mono- and bis-pinene-[5,6]-bipyridines are useful ligands in asymmetric copper-catalyzed cyclopropanation by styrenes. Copper complexes were prepared either in situ or prior to the reaction. The catalytic reaction of styrene with ethyl diazoacetate and Cu-11b yields ethyl trans-phenylcyclopropane carboxylate in >99% yield and 87% e.e. at 0°C. The corresponding cis-configured cyclopropane was produced with an e.e. of 90%. The cis/trans ratio is 22:78. Other ligands of this series are less effective. Various olefins were tested as substrates but exo-methylene olefins show the best results. (C) 2000 Elsevier Science Ltd.
