Calculate Digit Verification of CAS Registry Number 676617-25:
(8*6)+(7*7)+(6*6)+(5*6)+(4*1)+(3*7)+(2*2)+(1*5)=197
197 % 10 = 7
So 676617-25-7 is a valid CAS Registry Number.

Potential antimicrobial agents: Trifluoromethyl-10H-phenothiazines and ribofuranosides

Singh, Girwar,Kumar, Neeraj,Yadav, Ashok K.,Mishra

, p. 481 - 486 (2003)

The zinc salts of substituted 2-amino benzenethiols, on condensation with 2-chloro-3-nitro-5-trifluoromethyl benzene, in presence of sodium acetate and ethanol and subsequent formylation gave the corresponding 2-formamido-substituted diphenylsulfides. From them substituted 2-trifluoromethyl-10H-phenothiazines have been synthesized via Smiles rearrangement. Ribofuranosides α- and β- anomers were synthesized by the condensation of phenothiazines with sugar in toluene in presence of SnCl4 at 0°C and 155-160°C, respectively.
