1723-34-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1723-34-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,2 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1723-34:
(6*1)+(5*7)+(4*2)+(3*3)+(2*3)+(1*4)=68
68 % 10 = 8
So 1723-34-8 is a valid CAS Registry Number.

HIGH-TEMPERATURE ORGANIC SYNTHESIS XXXV. THERMAL REACTIONS OF DI(1-PROPENYL) SULFIDE

Ostroukhova, L. A.,Deryagina, E. N.,Korchevin, N. A.,Musorin, G. K.,Amosova, S. V.,Voronkov, M. G.

, p. 301 - 305 (2007/10/02)

The thermolysis of dipropenyl sulfide in a flow-type system in an atmosphere of nitrogen at 450-540 deg C leads to propenethiol, thiophene, methylthiophenes, and 2-ethylthiophene.The formation of the thiophene derivatives results from intramolecular radical cyclization of the initial sulfide.Dimethyl selenide (5-10 mole percent) substantially accelerates the thermolysis of dipropenyl sulfide, and the yield of 2-ethylthiophene at 450-480 deg C is increased appreciably.The high-temperature reactions of di(1-propenyl) sulfide with 2-halogenothiophenes and acetylene confirm that the propenethiol and thiophene derivatives are formed in parallel during the thermolysis of dipropenyl sulfide.
