Check Digit Verification of cas no

The CAS Registry Mumber 394729-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,4,7,2 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 394729-59:
(8*3)+(7*9)+(6*4)+(5*7)+(4*2)+(3*9)+(2*5)+(1*9)=200
200 % 10 = 0
So 394729-59-0 is a valid CAS Registry Number.

Preparation and application of polymer-supported π-allylpalladium complex as a chiral catalyst in the asymmetric allylic alkylation

Park,Han, Jin Wook,Seo, Hwimin,Jang, Hye-Young,Chung, Young Keun,Suh, Junghun

, p. 151 - 157 (2008/10/08)

Chiral ferrocenylphosphine-imines A-D were synthesized and grafted to polystyrene to afford polymeric ligands PA-PD. Ligands A-D and PA-PD were used as ligands in the palladium-catalyzed asymmetric allylic alkylation. In the homogeneous reactions, the best result was obtained when the ligand A was used (99% yield and 82% ee). In the heterogeneous reactions, the highest ee value (73%) in the first run was obtained when PA was used as a ligand. Considering the enantioselectivity and reusability, the best result was obtained in the case of PC. The recycling of the polymer-supported π-allylpalladium catalyst gave unsatisfactory results: it can be reused three times with moderate enantioselectivities (60-70% ee).
