Check Digit Verification of cas no

The CAS Registry Mumber 138995-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,9 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138995-92:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*5)+(2*9)+(1*2)=193
193 % 10 = 3
So 138995-92-3 is a valid CAS Registry Number.

Synthesis and antifungal activities of some new tetrahydro-2H-1,3,5-thiadiazine-2-thiones

Ertan,Ayyildiz,Yulug

, p. 1182 - 1185 (2007/10/02)

A number of new 3-benzyl-5-[α-(substituted)carboxymethyl]-tetrahydro-2H- 1,3,5-thiadiazine-2-thiones has been synthesized as prodrugs by incorporating the amine group of some amino acid into tetrahydro-2H-1,3,5-thiadiazine-2-thione ring. The compounds have been prepared by the reactions of benzylamine with potassium hydroxide, carbon disulphide formaldehyde and various amino acids. The structures of the compounds have been elucidated by UV, IR, 1H-NMR, mass spectra and elementary analysis. The in vitro activity of these compounds against yeast-like fungi (Candida albicans, C. parapsilosis, C. pseudotropicalis, C. stellatoidea) was investigated by tube dilution method. Their minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) values were determined. All the compounds were found to be active between 3.12- 12.5 μg/ml against the four fungi tested.
