285133-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 285133-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,5,1,3 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 285133-45:
(8*2)+(7*8)+(6*5)+(5*1)+(4*3)+(3*3)+(2*4)+(1*5)=141
141 % 10 = 1
So 285133-45-1 is a valid CAS Registry Number.

Transformations of 2-alkylidene-4-oxothiazolidine vinyl bromides initiated by bromophilic attack of neutral and anionic nucleophiles

Baranac-Stojanovi?, Marija,Tatar, Jovana,Stojanovi?, Milovan,Markovi?, Rade

experimental part, p. 6873 - 6884 (2010/10/01)

Vinyl bromides derived from 2-alkylidene-4-oxothiazolidines represent a class of vinyl halides, which readily undergo a bromophilic attack by a range of nucleophiles. With Ph3P, AcS-, CN-, I -, F-, Ac

Regioselective synthesis of new 5-ethoxycarbonylmethyl-4-oxothiazolidin-2-ylidene bromides and rearrangement reaction thereof

Markovi?, Rade,Baranac, Marija

, p. 607 - 610 (2007/10/03)

(Z)-5-Substituted-2-alkylidene-4-oxothiazolidine derivatives 2a-c were regioselectively brominated to afford the new, synthetically useful vinyl bromides 3a-c. They undergo novel rearrangement reaction to provide 4-oxothiazolidine derivatives 5a-c containing two fully conjugated exocyclic double bonds. Extremely clean and efficient derivatization of 2a-c to 5a-c was also achieved by a one-pot three-step sequence under mild experimental conditions without isolation of vinyl bromides 3a-c.
