1438397-04-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1438397-04-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,3,9 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1438397-04:
(9*1)+(8*4)+(7*3)+(6*8)+(5*3)+(4*9)+(3*7)+(2*0)+(1*4)=186
186 % 10 = 6
So 1438397-04-6 is a valid CAS Registry Number.

On aromatic electrophilic substitution promoted by in situ generated thionium ions
Amici, Rosanaribeiro,Di Vitta, Claudio,Marzorati, Liliana
, p. 798 - 802 (2013/04/23)
α-Sulfanylated α-arylacetates and -thioacetates were prepared via ethylthiomethylation reaction of aromatic compounds. These aromatic electrophilic substitutions were performed by in situ generation of the thionium ions by reacting trifluoroacetic anhydri
