Check Digit Verification of cas no

The CAS Registry Mumber 328242-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,2,4 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 328242-17:
(8*3)+(7*2)+(6*8)+(5*2)+(4*4)+(3*2)+(2*1)+(1*7)=127
127 % 10 = 7
So 328242-17-7 is a valid CAS Registry Number.

Mechanistic dichotomy in the asymmetric allylation of aldehydes with allyltrichlorosilanes catalyzed by chiral pyridine N-oxides

Malkov, Andrei V.,Stoncius, Sigitas,Bell, Mark,Castelluzzo, Fabiomassimo,Ramirez-Lopez, Pedro,Biedermannova, Lada,Langer, Vratislav,Rulisek, Lubomir,Kocovsky, Pavel

, p. 9167 - 9185 (2013/07/26)

Detailed kinetic and computational investigation of the enantio- and diastereoselective allylation of aldehydes 1 with allyltrichlorosilanes 5, employing the pyridine N-oxides METHOX (9) and QUINOX (10) as chiral organocatalysts, indicate that the reaction can proceed through a dissociative (cationic) or associative (neutral) mechanism: METHOX apparently favors a pentacoordinate cationic transition state, while the less sterically demanding QUINOX is likely to operate via a hexacoordinate neutral complex. In both pathways, only one molecule of the catalyst is involved in the rate- and selectivity-determining step, which is supported by both experimental and computational data. Copyright

A pineno-salen type catalyst for the enantioselective Nozaki-Hiyama-Kishi reaction

Dhondge, Attrimuni P.,Shaikh, Ajam C.,Chen, Chinpiao

experimental part, p. 723 - 733 (2012/08/29)

A new class of pineno-salen type ligands 10, 11, 17, 20, 23, and 24 has been developed. The catalyst formed from chromium(II)-10 promotes the enantioselective Nozaki-Hiyama-Kishi allylation of alkyl and aryl aldehydes using allyl bromide. Notably, the asymmetric addition of vinyl halide to benzaldehyde was achieved with 24% ee.
