128102-79-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128102-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,0 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128102-79:
(8*1)+(7*2)+(6*8)+(5*1)+(4*0)+(3*2)+(2*7)+(1*9)=104
104 % 10 = 4
So 128102-79-4 is a valid CAS Registry Number.

Cycloaddition Elimination Reactions of 4-Aryl-5-arylimino-1,2,4-dithiazolidin-3-ones (Mustard Oil Oxides)

Tittelbach, Franz

, p. 579 - 592 (2007/10/02)

4-Aryl-5-arylimino-1,2,4-dithiazolidin-3-ones (1) react with isocyanates, isothiocyanates, and cyanic acid esters by exchange of the COS-part from 1 affording thiadiazole and dithiazole derivatives 4, 5, 6, or 12.The reaction products are able to give fur

Synthesis and Reactivity of 1,2,4-Oxathiazolidin-3-imines

L'abbe, Garrit,Buelens, Karin

, p. 1993 - 1995 (2007/10/02)

Thiatriazolin 4a decomposes in acetone and yields a thermolabile crystalline material, identified as the 1,2,4-oxathiazole derivative 6a on the basis of ir, 1H and 13C nmr spectroscopy.It degrades to 7a in the crystalline state as well in solution.Cycloaddition-eliminiation reactions of 6a with isothiocyanates proceed rapidly and furnish the same products as previously obtained from 4a.Some other reactions of 4 with carbonyl compounds were briefly investigated and provide evidence for the formation of unstable 1,2,4-oxathiazolidines.
