141656-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141656-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 141656-28:
(8*1)+(7*4)+(6*1)+(5*6)+(4*5)+(3*6)+(2*2)+(1*8)=122
122 % 10 = 2
So 141656-28-2 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.
