132401-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132401-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,0 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132401-25:
(8*1)+(7*3)+(6*2)+(5*4)+(4*0)+(3*1)+(2*2)+(1*5)=73
73 % 10 = 3
So 132401-25-3 is a valid CAS Registry Number.

A new synthetic route to α-hydroxy butyrolactones
Jarvis,Wells,Kaufmann
, p. 1079 - 1082 (2007/10/02)
α-Oxocarboxylic acids react with olefins under acid conditions to give α-hydroxy butyrolactones (3-hydroxy-2-oxotetrahydrofurans) which can be readily dehydrated to give α,β-unsaturated butyrolactones 2-oxo-2,5-dihydrofurans.
