Check Digit Verification of cas no

The CAS Registry Mumber 174622-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,6,2 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 174622-82:
(8*1)+(7*7)+(6*4)+(5*6)+(4*2)+(3*2)+(2*8)+(1*2)=143
143 % 10 = 3
So 174622-82-3 is a valid CAS Registry Number.

Synthesis and evaluation of some substituted 1,3,4-thiadiazole derivatives

Gulerman,Rollas,Ulgen,Gorrod

, p. 461 - 463 (2007/10/02)

5-[p-(acetylamino)phenyl]-2-substitutedamino-1,3,4-thiadiazole derivatives were prepared by the cyclisation reaction of sulphuric acid on 1-[p-(aminoacetyl)phenyl]-4-alkyl/arylthiosemicarbazides. The intermediate thio semicarbazides were formed by the condensation of p-(acetylamino)benzoylhydrazine with corresponding isothiocyanates. The structures of the compounds were elucidated by use of their IR, 1H NMR and mass spectral data.
