Check Digit Verification of cas no

The CAS Registry Mumber 1198619-74-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,6,1 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1198619-74:
(9*1)+(8*1)+(7*9)+(6*8)+(5*6)+(4*1)+(3*9)+(2*7)+(1*4)=207
207 % 10 = 7
So 1198619-74-7 is a valid CAS Registry Number.

Synthesis, characterization and derivatization of some novel types of mono- and bis-imidazolidineiminothiones and imidazolidineiminodithiones with antitumor, antiviral, antibacterial and antifungal activities - part I

El-Sharief, Ahmed M. Sh.,Moussa, Ziad

experimental part, p. 4315 - 4334 (2009/12/24)

Halogenated and alkylated N-arylcyanothioformanilides were reacted with the nucleophilic reagents triethylamine, hydrazine and diphenyldiazomethane to produce N-arylcyanothioformanilide ammonium salts, a thiosemicarbazide and a 2-(arylamino)-3,3-diphenylacrylonitrile, respectively. They also underwent several types of electrophilic reactions with aryl-, arylbisisocyanates and arylisothiocyanates to yield mono- and bis-imidazolidineiminothiones and imidazolidineiminodithiones. Treatment of imidazolidineiminothiones with hydrogen sulfide, substituted ortho-phenylenediamines and thiocarbohydrazide afforded the corresponding thiohydantoin, quinoxaline and imidazotriazine derivatives. Several of the synthesized products were subjected to in vitro biological evaluation against antitumor, antiviral, antimicrobial and antifungal strains. Most tested compounds showed significant activities.
