1542-14-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1542-14-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1542-14:
(6*1)+(5*5)+(4*4)+(3*2)+(2*1)+(1*4)=59
59 % 10 = 9
So 1542-14-9 is a valid CAS Registry Number.

Thermal reactions of hexafluorobutadiene and hexafluorocyclobutene with elemental sulphur

Kazmina, N. B.,Mysov, E. I.,Aerov, A. F.,Kagramanova, E. M.

, p. 203 - 208 (2007/10/02)

Hexafluorobuta-1,3-diene and hexafluorocyclobutene interact with elemental sulphur under conditions of mutual conversion (>/= 280 deg C) to give the same products, hexafluoro-3,6-dihydro-1,2-dithiine (1), hexafluorothiolene-3 (2) and hexafluorothiolanethione (3).The product composition and ratio depend on the reaction conditions.Dithiine 1 and thiolene 2 were formed in competitive reactions.Their thermal stability and the retrocycloaddition reaction of dithiine 1 have been studied.The latter reaction results in thiolene 2 in addition to the formation of hexafluorocyclobutene.This is consistent with a stepwise mechanism for the retrocycloaddition as well as the cycloaddition reaction.
