144688-34-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144688-34-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,8 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144688-34:
(8*1)+(7*4)+(6*4)+(5*6)+(4*8)+(3*8)+(2*3)+(1*4)=156
156 % 10 = 6
So 144688-34-6 is a valid CAS Registry Number.

Enzymatic Resolution of 1,2-Diols: Comparison between Hydrolysis and Transesterification Reactions
Bosetti, Aldo,Bianchi, Daniele,Cesti, Pietro,Golini, Paolo,Spezia, Sandro
, p. 2395 - 2398 (2007/10/02)
A new practical procedure for the enzymatic resolution of 1,2-diols 1a-e has been developed by lipase-catalysed regio- and enantio-selective esterification using anhydrides as acylating agents in organic solvents.
