The CAS Registry Mumber 1052274-38-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,2,2,7 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1052274-38:
(9*1)+(8*0)+(7*5)+(6*2)+(5*2)+(4*7)+(3*4)+(2*3)+(1*8)=120
120 % 10 = 0
So 1052274-38-0 is a valid CAS Registry Number.

Asymmetric addition of diethylzinc to ketones promoted by tartaric acid derivatives

Hui, Ailing,Zhang, Jintang,Wang, Zhiyong

, p. 2374 - 2384 (2008/09/21)

The preparation of new sulfonamide ligands derived from L-tartaric acid and camphor sulfonyl chloride are described. The employment in the titanium tetraisopropoxide-promoted enantioselective addition of diethylzinc to ketones has been studied. The best enantiomeric excess is up to 99% with 7 mol% catalyst loading at room temperature. Copyright Taylor & Francis Group, LLC.
