7670-39-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7670-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,7 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7670-39:
(6*7)+(5*6)+(4*7)+(3*0)+(2*3)+(1*9)=115
115 % 10 = 5
So 7670-39-5 is a valid CAS Registry Number.

Synthesis of 1,4-oxathian-2-ones by triton B-catalyzed one-pot reaction of epoxides with ethyl mercaptoacetate

Wechteti, Lassaad,Mekni, Nejib Hussein,Romdhani-Younes, Moufida

, p. 187 - 191 (2018/07/13)

A rapid one-pot reaction of epoxides with ethyl mercaptoacetate furnishing 1,4-oxathian-2-ones in the presence of a catalytic amount of eco-friendly triton B is reported. High regioselectivity is due to the nucleophilic attack on the less sterically hinde

Preparation and Stability of 1,4-Oxathian-2-ones

Koskimies, Jorma K.

, p. 101 - 108 (2007/10/02)

Several methods of preparation of various substituted 1,4-oxathian-2-ones are described, including the acid-catalyzed ring closure of δ-hydroxy acids, prepared via α-halo ketones or α-halo acids, and the base-catalyzed ring closure of β-haloethyl thioglycolate. 1,4-Oxathian-2-one is completely hydrolyzed in D2O to the hydroxy acid at a rate comparable to the hydrolysis of δ-valerolactone.The rate of the lactonization is estimated to be ca. 100 times smaller in oxathianone than in valerolactone.
