107326-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107326-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,3,2 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107326-19:
(8*1)+(7*0)+(6*7)+(5*3)+(4*2)+(3*6)+(2*1)+(1*9)=102
102 % 10 = 2
So 107326-19-2 is a valid CAS Registry Number.

Sequential ring expansion and ketene elimination reactions in the novel rhodium(I)-catalyzed carbonylation of thiazolidines

Khumtaveeporn, Kanjai,Alper, Howard

, p. 5662 - 5666 (2007/10/02)

1,3-Thiazolidines react with carbon monoxide, in the presence of catalytic quantities of chloro(1,5-cyclooctadiene)rhodium(I) dimer and potassium iodide, to give thiazolidinones in 56-88% yields. Reaction in the absence of KI afforded the six-membered ring thiazin-3-one. The rhodium(I) complex can catalyze the quantitative conversion of the thiazin-3-one to the thiazolidinone under carbon monoxide, with ketene as the reaction by-product. The conversion of thiazolidines to thiazolidinones involves a novel regiospecific insertion of carbon monoxide into one of two ring carbon-nitrogen bonds, as well as a metal-catalyzed ketene elimination process.
