Check Digit Verification of cas no

The CAS Registry Mumber 42542-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,4 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42542-64:
(7*4)+(6*2)+(5*5)+(4*4)+(3*2)+(2*6)+(1*4)=103
103 % 10 = 3
So 42542-64-3 is a valid CAS Registry Number.

Synthesis of uracil derivatives by oxidation of Fischer tungsten-carbene uracil complexes

Sala, Giorgio Della,Artillo, Antonietta,Ricart, Susagna,Spinella, Aldo

, p. 1623 - 1627 (2007)

A study on the oxidation of Fischer tungsten-carbene uracil complexes has been carried out. Several commonly used oxidants gave results strongly influenced by the presence of substituent on nitrogen atoms. In particular, usual oxidants failed in the oxidation of 3-alkyl uracil carbene complexes. Finally, we showed that t-butyl hydroperoxide is able to oxidize successfully also 3-alkyl uracil carbene complexes and can be used as a good alternative to the other methods.
