Check Digit Verification of cas no

The CAS Registry Mumber 147047-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,0,4 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 147047-91:
(8*1)+(7*4)+(6*7)+(5*0)+(4*4)+(3*7)+(2*9)+(1*1)=134
134 % 10 = 4
So 147047-91-4 is a valid CAS Registry Number.

Redox-Neutral Synthesis of Selenoesters by Oxyarylation of Selenoalkynes under Mild Conditions

Baldassari, Lucas L.,Mantovani, Anderson C.,Senoner, Samuel,Maryasin, Boris,Maulide, Nuno,Lüdtke, Diogo S.

, p. 5881 - 5885 (2018)

An approach for the mild synthesis of selenoesters starting from selenoalkynes through an acid-catalyzed, redox-neutral oxyarylation reaction is reported. Br?nsted acid activation of a selenoalkyne leads to a selenium-stabilized vinyl cation, which is cap
