715-39-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 715-39-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 715-39:
(5*7)+(4*1)+(3*5)+(2*3)+(1*9)=69
69 % 10 = 9
So 715-39-9 is a valid CAS Registry Number.

2,2,6,6-Tetramethylpiperidine-catalyzed, ortho-selective chlorination of phenols by sulfuryl chloride

Saper, Noam I.,Snider, Barry B.

, p. 809 - 813 (2014/04/03)

2,2,6,6-Tetramethylpiperidine (TMP)-catalyzed (1- 10%) chlorinations of phenols by SO2Cl2 in aromatic solvents are more ortho selective than with primary and less hindered secondary amine catalysts. Ortho-selective chlorination is successful even with electron deficient phenols such as 2-hydroxybenzaldehyde and 2'- hydroxyacetophenone. Notably, ortho selectivity increases with the reaction temperature. On the other hand, tetraalkylammonium chloride-catalyzed chlorinations are moderately para selective.

STRUCTURES OF MELLEOLIDES B-D, THREE ANTIBACTERIAL SESQUITERPENOIDS FROM ARMILLARIA MELLEA

Arnone, Alberto,Cardillo, Rosanna,Nasini, Gianluca

, p. 471 - 474 (2007/10/02)

Key Word Index-Armillaria mellea; Basidiomycete; secondary metabolites; protoilludane derivatives; structural determination.The structures of melleolides B-D, three new protoilludene sesquiterpenoid O-methylorsellinates isolated from a culture of Armillaria mellea, have been elucidated on the basis of chemical and spectral data.

Depsidone Synthesis. Part 16. Benzophenone-Grisa-3',5'-diene-2',3-dione-depsidone Interconversion: a New Theory of Depsidone Biosynthesis

Sala, Tony,Sargent, Melvyn V.

, p. 855 - 869 (2007/10/02)

The synthesis of a number of grisa-3',5'-diene-2',3-diones by oxidative coupling of substituted 2,2'-dihydroxy-4-methoxybenzophenones is described.The rearrangement of these grisadienediones to depsidones under basic, acidic, and thermal conditions is des
