Check Digit Verification of cas no

The CAS Registry Mumber 221650-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,5 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221650-77:
(8*2)+(7*2)+(6*1)+(5*6)+(4*5)+(3*0)+(2*7)+(1*7)=107
107 % 10 = 7
So 221650-77-7 is a valid CAS Registry Number.

Synthesis and electrohydrodimerization of meta-substituted thiocinnamic acid S-esters

Gruber, Jonas,Camilo, Fernanda F.,Arantes, Ana C. M.

, p. 389 - 393 (2007/10/03)

The synthesis of the novel m-substituted S-methyl thiocinnamates 1-4 is described. Cathodic reductions of S-esters 1 - 3, carried out at constant potentials corresponding to their first voltammetric E(pc), in a polar aprotic solvent, led exclusively to th
