144491-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144491-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144491-19:
(8*1)+(7*4)+(6*4)+(5*4)+(4*9)+(3*1)+(2*1)+(1*9)=130
130 % 10 = 0
So 144491-19-0 is a valid CAS Registry Number.

Preparation of optically pure L-2-hydroxyaldehydes with yeast transketolase
Effenberger, Franz,Null, Volker,Ziegler, Thomas
, p. 5157 - 5160 (2007/10/02)
L-2-Hydroxyaldehydes L-3 with a great variety of substituents in 3-position are obtained in good chemical and excellent optical yields by kinetic resolution in the transketolase-catalyzed reaction of racemic 2-hydroxyaldehydes with lithium hydroxypyruvate
