131175-58-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131175-58-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131175-58:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*5)+(2*5)+(1*8)=101
101 % 10 = 1
So 131175-58-1 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.
