14739-28-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14739-28-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,3 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 14739-28:
(7*1)+(6*4)+(5*7)+(4*3)+(3*9)+(2*2)+(1*8)=117
117 % 10 = 7
So 14739-28-7 is a valid CAS Registry Number.

Reaction of 1,3-Oxathiolium Salts with Three Types of Ring Expansion Reagents on a Nitrogen Atom

Yonemoto, Katsumi,Honda, Kazumasa,Shibuya, Isao,Taguchi, Yoichi,Tsuchiya, Tohru,Yasumoto, Masahiko

, p. 668 - 673 (2007/10/02)

The ring expansion reactions of 1,3-oxathiolium salts (1) using NaN3 and an I2-aq NH3 system resulted exclusively in the formatiom of 1,4,2-oxathiazines (3) by incorporation of a nitrogen atom into the C-O bond in 1.On the other hand, the reaction of 1 wi

Reactions of N,N-Dialkyl-N'-arylthioureas with α-Haloketones and of 2-Substituted Imino-1,3-oxathioles with Heterocumulenes

Singh, Harjit,Ahuja, A. S.,Malhotra, N.

, p. 1019 - 1022 (2007/10/02)

N,N-Dialkyl-N'-arylthioureas react with phenacyl halides to give 2-arylimino-5-phenyl-1,3-oxathioles (I), 3-aryl-2-arylimino-4-phenyl-4-thiazolines (III), aryl isothiocyanates and N,N'-diarylthioureas.I reacts with heterocumulenes like phenyl isocyanate and phenyl isothiocyanate to give 3,4-diaryl-2-arylimino-4-thiazolines, N,N'-diarylthioureas, arylacetylenes and COS or CO2.Mechanisms of formation of the various products have been proposed, based on TLC monitoring at regular time intervals.These are independently supported by chemical reactions.
