Calculate Digit Verification of CAS Registry Number 117664-60:
(8*1)+(7*1)+(6*7)+(5*6)+(4*6)+(3*4)+(2*6)+(1*0)=135
135 % 10 = 5
So 117664-60-5 is a valid CAS Registry Number.

Intramolecular Chemoselective Heterocyclisation of Oxothiazolidin-5yl N-Aryldithiocarbamates to Fungitoxic 1,3-Dithiolo-1,3-Oxathiolo- and Thiazolo-thiazoles

Singh, H.,Mishra, A. R.,Yadav, L. D. S.

, p. 1200 - 1202 (2007/10/02)

Substituted 1,3-dithiolothiazoles (IVa-d), 1,3-oxathiolothiazoles (Va-d) and thiazolothiazoles (VIa-d) have been synthesised by the intramolecular chemoselective heterocyclisation of 4-oxathiazolidin-5-yl N-aryldithiocarbamates (IIIa-d) with conc.H2SO4, CH3I and NaOH, respectively.The compounds III-VI were compared with Dithiane M-45 for their fungitoxicity against A. niger and F. oxysporium.Based on screening data, a possible structure-activity relationship has been deduced.
