Check Digit Verification of cas no

The CAS Registry Mumber 193561-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,5,6 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 193561-43:
(8*1)+(7*9)+(6*3)+(5*5)+(4*6)+(3*1)+(2*4)+(1*3)=152
152 % 10 = 2
So 193561-43-2 is a valid CAS Registry Number.

Chemistry of thioacylsilanes - Part 11. Cyclic and open chain α-silyl vinyl sulfides as precursors of thioannulated cyclopentenones and thiofunctionalized enones

Bonini, Bianca F.,Comes Franchini, Mauro,Fochi, Mariafrancesca,Mazzanti, Germana,Ricci, Alfredo

, p. 7897 - 7910 (2007/10/03)

Cyclic and open chain α-silyl vinyl sulfides, obtained from thioacylsilanes, react with acid chlorides in the presence of Lewis acid to give thioannulated cyclopentenones and thiofunctionalized enones. The effect of the substituents at silicon on these reactions has been investigated.
