131080-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131080-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,8 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131080-72:
(8*1)+(7*3)+(6*1)+(5*0)+(4*8)+(3*0)+(2*7)+(1*2)=83
83 % 10 = 3
So 131080-72-3 is a valid CAS Registry Number.

Enantioselective Route to γ-Butyrolactones: Chiral Auxiliary Mediated Amide Alkylation and Iodolactonization
Najdi, Samir,Reichlin, Daniel,Kurth, Mark J.
, p. 6241 - 6244 (2007/10/02)
A number of chiral, γ,δ-unsaturated amides (1 and 2) have been prepared and their subsequent alkylation and iodolactonization to γ-butyrolactones (3) investigated.
