Check Digit Verification of cas no

The CAS Registry Mumber 6007-26-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,0 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6007-26:
(6*6)+(5*0)+(4*0)+(3*7)+(2*2)+(1*6)=67
67 % 10 = 7
So 6007-26-7 is a valid CAS Registry Number.

Exploiting the 1,3-dithiane of 2-oxopropanenitrile oxide to limit competing dimerization in 1,3-dipolar cycloaddition reactions

Barrow, Stuart J.,Easton, Christopher J.,Savage, G. Paul,Simpson, Gregory W.

, p. 2175 - 2178 (1997)

The 1,3-dithiane of 2-oxopropanenitrile oxide is less prone to dimerization than the parent compound and, as a consequence, it undergoes more efficient cycloaddition reactions with a range of mono- and 1,1- and 1,2-di-substituted alkenes.

Pyrazine biosynthesis in corynebacterium glutamicum

Dickschat, Jeroen S.,Wickel, Susanne,Bolten, Christoph J.,Nawrath, Thorben,Schulz, Stefan,Wittmann, Christoph

supporting information; experimental part, p. 2687 - 2695 (2010/08/07)

The volatile compounds released by Corynebacterium glutamicum were collected by use of the CLSA technique (closed-loop stripping apparatus) and analysed by GC-MS. The headspace extracts contained several acyloins and pyrazines that were identified by their synthesis or comparison to commercial standards. Feeding experiments with [2H7]acetoin resulted in the incorporation of labelling into trimethylpyrazine and tetramethylpyrazine. Several deletion mutants targeting genes of the primary metabolism, were constructed to elucidate the biosynthetic pathway to pyrazines in detail. A deletion mutant of the ketol-acid reductoisomerase was not able to convert the acetoin precursor (S)2-acetolactate into the pathway intermediate (R)-2,3-dihydroxy-3-methylbutanoate to the branched amino acids. This mutant requires valine, leucine, and isoleucine for growth and produces significantly higher amounts and more different compounds of the acyloin and pyrazine classes. Gene deletion of the acetolactate synthase (AS) resulted in a mutant that is not able to convert pyruvate into (5)-2-acetolactate. This mutant also requires branched amino acids and produces only very small amounts of pyrazines likely from valine via the valine biosynthetic pathway operating in reverse order. A ΔASΔKR double mutant was constructed that does not produce any pyrazines at all. These results open up a detailed biosynthetic model for the formation of alkylated pyrazines via acyloins.

Externally sensitized mesolytic fragmentations in dithiane-ketone adducts

Gustafson, Tiffany P.,Kurchan, Alexei N.,Kutateladze, Andrei G.

, p. 6574 - 6580 (2007/10/03)

The apparent activation enthalpies, ΔH≠, for externally sensitized mesolytic fragmentations in benzophenone-dithiane adducts were obtained in variable temperature photolyses and compared with DFT activation barriers calculated for β-scission in the corresponding oxygen-centered radicals. The results of these experimental and theoretical studies further support the mechanism in which deprotonation of the hydroxy-group, in the transient cation radical, is coupled with intramolecular electron transfer furnishing the O-centered radical, which subsequently fragments. The quantum yields of fragmentation increase for higher alkyl substituted dithiane adducts.
