119986-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119986-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,8 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119986-67:
(8*1)+(7*1)+(6*9)+(5*9)+(4*8)+(3*6)+(2*6)+(1*7)=183
183 % 10 = 3
So 119986-67-3 is a valid CAS Registry Number.

Efficient MnIII-mediated synthesis of functionalized trans-3,4-disubstituted-γ-butyrolactones
Méou, Alain,Lamarque, Laurent,Brun, Pierre
, p. 5301 - 5304 (2002)
The MnIII-induced addition of malonic acid (instead of acetic acid) to cinnamic esters affords in one step functionalized trans-3,4-disubstituted-γ-butyrolactones in a greatly improved yield which can be further optimized by conducting the reaction in either acetic or formic acid, depending on the substrate.
