Check Digit Verification of cas no

The CAS Registry Mumber 1082072-42-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,2,0,7 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1082072-42:
(9*1)+(8*0)+(7*8)+(6*2)+(5*0)+(4*7)+(3*2)+(2*4)+(1*2)=121
121 % 10 = 1
So 1082072-42-1 is a valid CAS Registry Number.

New highly efficient aziridine-functionalized tridentate sulfinyl catalysts for enantioselective diethylzinc addition to carbonyl compounds

Lesniak, Stanislaw,Rachwalski, Michal,Sznajder, Ewelina,Kielbasinski, Piotr

experimental part, p. 2311 - 2314 (2010/03/04)

New tridentate enantiomerically pure heteroorganic catalysts, containing hydroxyl, sulfinyl, and aziridine moieties, have proven to be highly efficient in the enantioselective diethylzinc addition to aryl and alkyl aldehydes to give the desired products in very high yields (up to 99%) and with ee's up to 97%. The influence of the stereogenic centers located on the sulfinyl sulfur atom and in the aziridine moiety on the stereochemical course of the reaction are discussed.
