Check Digit Verification of cas no

The CAS Registry Mumber 178151-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,1,5 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 178151-42:
(8*1)+(7*7)+(6*8)+(5*1)+(4*5)+(3*1)+(2*4)+(1*2)=143
143 % 10 = 3
So 178151-42-3 is a valid CAS Registry Number.

Stereodivergent approach to both c2,8a-syn and c2,8a-anti relative stereochemical manifolds in the lepadin family via a ticl4-promoted aza-[3+3] annulation

Li, Gang,Carlson, Lauren J.,Sagamanova, Irina K.,Slafer, Brian W.,Hsung, Richard P.,Gilardi, Claudio,Sklenicka, Heather M.,Sydorenko, Nadiya

scheme or table, p. 2905 - 2914 (2010/03/30)

Details in developing a stereodivergent approach to the lepadin family and establishing an entry to both C2,8a-syn and C2,8a-anti relative stereochemical manifolds through a common intermediate are described here. This works paves the foundation for const

Asymmetric catalysis via chiral aziridines

Tanner, David,Harden, Adrian,Johansson, Fredrik,Wyatt, Paul,Andersson, Pher G.

, p. 361 - 368 (2007/10/03)

The chiral bis(aziridines) 4, 6 and 7 have been synthesized and evaluated as chelating ligands for a variety of asymmetric transformations mediated by metals. The processes studied were the asymmetric addition of osmium tetroxide to olefins, copper-catalyzed asymmetric cyclopropanation and aziridination, palladium-catalyzed asymmetric allylic alkylation and asymmetric 1,2-addition of organolithium reagents to imines. In the best cases an enantiomeric excess >95% was obtained. Acta Chemica Scandinavica 1996.
