Check Digit Verification of cas no
The CAS Registry Mumber 42848-06-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,4 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42848-06:
(7*4)+(6*2)+(5*8)+(4*4)+(3*8)+(2*0)+(1*6)=126
126 % 10 = 6
So 42848-06-6 is a valid CAS Registry Number.

Isomerization processes in the synthesis of asymmetric allyl chalcogenides

Allyl-propenyl rearrangement (prototropic isomerization) occurs in the synthesis of allyl organyl chalcogenides in a hydrazine hydrate - KOH system with a 6 - 10-fold molar excess of KOH. Specificities of the rearrangement that depend on the nature of the chalcogen were studied.
Structure-Stability Relationships in Vinyl Sulfides. I. On the Stable Conformations of Vinyl Sulfides
Virtanen, Reijo
, p. 313 - 327 (2007/10/02)
A thermodynamic and 13C NMR spectroscopic study of the structures of the less stable rotamers of alkyl vinyl sulfides have been performed.It has been shown that the less stable rotamer of methyl vinyl sulfide has the planar s-trans configuration and the proportion of this is about 20percent.The energy difference between the planar s-cis and s-trans is about 3.5 kJ mol-1.Ethyl vinyl sulfide is almost an equimolar mixture of the planar s-cis and s-trans conformations.The 13C NMR data showed that the p-? cojugation in the compounds that could not adopt any of the planar arrangements was decreased.In alkyl 1-propenyl sulfides, the stabilizing interaction between the methyl group and the S atom cis to each other was ca.1.8 kJ mol-1.The most probable choice for the most stable conformation of di-1-propenyl sulfides is the planar (or nearly planar) s-trans,s-trans one.
