592551-69-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 592551-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,2,5,5 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 592551-69:
(8*5)+(7*9)+(6*2)+(5*5)+(4*5)+(3*1)+(2*6)+(1*9)=184
184 % 10 = 4
So 592551-69-4 is a valid CAS Registry Number.

Enantioselective deprotonation of ketones using a novel heterodimer chiral amide base
Amedjkouh, Mohamed
, p. 577 - 579 (2004)
A novel heterodimer chiral base system has been prepared and reacted with a series of prochiral ketones in the presence of TMSCl to give efficient formation of the corresponding enol ethers in an enantiomeric excess up to 85%.
