Check Digit Verification of cas no
The CAS Registry Mumber 55704-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,0 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55704-78:
(7*5)+(6*5)+(5*7)+(4*0)+(3*4)+(2*7)+(1*8)=134
134 % 10 = 4
So 55704-78-4 is a valid CAS Registry Number.

Synthesis and anthelmintic activity of 7-hydroxy-5-oxo-5H-thieno[3,2- b]pyran-6-carboxanilides and -6-thiocarboxanilides
Plant,Harder,Mencke,Bertram
, p. 351 - 358 (2007/10/03)
7-Hydroxy-5-oxo-5H-thieno[3,2-b]pyran-6-carboxanilides and -6- thiocarboxanilides represent a novel series of anthelmintic compounds, with broad-spectrum activity against important parasitic nematodes in sheep and dogs. In particular, an improved efficacy against Trichostrongylus colubriformis in sheep over the related 3-carbamoyl-4-hydroxycoumarins has been noted. New synthetic routes to the key intermediate, 7- hydroxythieno[3,2-b]pyran-5-one, have been developed.
