Check Digit Verification of cas no

The CAS Registry Mumber 159041-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,0,4 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 159041-93:
(8*1)+(7*5)+(6*9)+(5*0)+(4*4)+(3*1)+(2*9)+(1*3)=137
137 % 10 = 7
So 159041-93-7 is a valid CAS Registry Number.

Enantioselective Allylation of Ketone-Derived Benzoylhydrazones: Practical Synthesis of Tertiary Carbinamines

Berger, Richard,Duff, Keiko,Leighton, James L.

, p. 5686 - 5687 (2007/10/03)

A highly practical method for the enantioselective allylation of ketone-derived benzoylhydrazones has been developed. The previously reported strained silacycle reagent 1 reacts with a wide variety of benzoylhydrazones to give the hydrazide products with

Asymmetric hydrogenation method of a ketonic compound and derivative

-

, (2008/06/13)

The present invention relates to a process for the asymmetric hydrogenation of a ketonic compound and derivative. The invention relates to the use of optically active metal complexes as catalysts for the asymmetric hydrogenation of a ketonic compound and derivative. The process for the asymmetric hydrogenation of a ketonic compound and derivative is characterized in that the asymmetric hydrogenation of said compound is carried out in the presence of an effective amount of a metal complex comprising as ligand an optically active diphosphine corresponding to one of the following formulae: STR1
