Check Digit Verification of cas no
The CAS Registry Mumber 1756-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1756-18:
(6*1)+(5*7)+(4*5)+(3*6)+(2*1)+(1*8)=89
89 % 10 = 9
So 1756-18-9 is a valid CAS Registry Number.

Kinetics and Mechanism of the Oxidation of Unsaturated Carboxylic Acids by Methyltributylammonium Permanganate in Methylene Chloride Solutions
Perez-Benito, Joaquin F.,Lee, Donald G.
, p. 3239 - 3243 (2007/10/02)
The product obtained when permanganate is reduced by unsaturated carboxylic acids under anhydrous conditions is manganese(III).The rate of reaction, which is subject to acid catalysis, exhibits a Hammet ρ value of 1.11 and inverse secondary isotope effects (kH/kD = 0.96-0.98) when the hydrogens on the double bond are replaced by deuterium.The involvement of a free-radical process is indicated by the formation of polymer during the oxidation of acrylic and methacrylic acids.The reaction is believed to be initiated by formation of an organometallic complex in which the double bond is a η2 ligand on manganese.Rearrangement of this complex results in the formation of a reactive manganate(V) cyclic diester, which undergoes a rapid (free-radical) reduction to manganese(III).
Synthesis of Enantiomerically Pure Forms of N-Acyl Derivatives of C-Methyl Analogues of the Aminodeoxy Sugar L-Acosamine from Noncarbohydrate Precursors

The 2S,3R diol 2a and the 3R α-ketol 5b, prepared in fermenting baker's yeast from cinnamaldehyde and α-methylcinnamaldehyde, are converted into the chiral N-trifluoroacetyl deoxy C-methyl-branched amino sugars 15b,c and 19b.Key intermediates in the synthesis are the C4 and C5 chiral aldehydes 9a and 17a and the α,β-unsaturated carbonyl compounds 11a and 18, which upon threo stereoselective addition of ammonia, eventually give 15b,c and 19b.The sterochemistry and the conformations of the aminodeoxy sugar derivatives and of the intermediate lactones are deduced byNMR studies.
