140630-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140630-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,3 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140630-39:
(8*1)+(7*4)+(6*0)+(5*6)+(4*3)+(3*0)+(2*3)+(1*9)=93
93 % 10 = 3
So 140630-39-3 is a valid CAS Registry Number.

A facile conversion of epoxides to β-halohydrins with silica gel-supported lithium halides

Kotsuki, Hiyoshizo,Shimanouchi, Tomoyasu

, p. 1845 - 1848 (1996)

A variety of epoxides are efficiently converted to the corresponding β-halohydrins with lithium halides supported on silica gel in dry media.

Visible-light-triggered Catalytic Halohydrin Synthesis from Epoxides and Trichloroacetonitrile by Copper and Iron Salts

Toda, Yasunori,Tanaka, Katsumi,Matsuda, Riki,Suga, Hiroyuki

supporting information, p. 1469 - 1471 (2019/12/02)

Preparation of vicinal halohydrins, in which copper or iron chlorides catalyze the ring-opening reaction of epoxides with visible light effectively, is described. The use of trichloroacetonitrile as a halogen source enables catalytic HCl generation under the mild conditions. This method can also be applied to the aziridine ring-opening reaction.

Trihaloisocyanuric Acid/Triphenylphosphine: An Efficient System for Regioselective Conversion of Epoxides into Vicinal Halohydrins and Vicinal Dihalides under Mild Conditions

De Andrade, Vitor S. C.,De Mattos, Marcio C. S.

, p. 1381 - 1388 (2016/05/19)

A new synthetic method has been developed for the regioselective conversion of epoxides to vicinal chloro-/bromohydrins and vicinal dihalides by reaction with the system trihaloisocyanuric acid/tri?phenylphosphine in acetonitrile under mild and neutral conditions. The reactions proceed smoothly in high yield at room temperature and at reflux, respectively, over a short time.
