53684-00-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53684-00-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,8 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53684-00:
(7*5)+(6*3)+(5*6)+(4*8)+(3*4)+(2*0)+(1*0)=127
127 % 10 = 7
So 53684-00-7 is a valid CAS Registry Number.

PH-functional o-phosphinophenols - Synthesis via methoxymethylethers and screening tests for Ni-catalyzed ethylene polymerization

Heinicke, Joachim,He, Mengzhen,Karasik, Andrej A.,Georgiev, Igor O.,Sinyashin, Oleg G.,Jones, Peter G.

, p. 379 - 390 (2007/10/03)

Various primary and secondary 2-phosphinoaryl methoxymethylethers were prepared via orthometallation of methyl- and methoxy-substituted aryl methoxymethylethers and subsequent reaction with aminochlorophosphines, followed by alcoholysis and reduction with excess LiAlH4. Incomplete reduction provides 2-methoxymethoxy-substituted cyclotetraphosphines, isolated and characterized by X-ray crystal structure analysis in one case. An example of the facile P-alkylation of primary to secondary representatives is also given. Secondary 2-phosphinophenols, obtained by selective cleavage of the MOM-protection group, and even the primary 2-phosphino-4-methylphenol react with Ni(COD)2 to form ethylene polymerization catalysts. 4-Methoxy groups cause a strong increase of the molecular weights and a bimodal molecular weight distribu tion of the polymerization products; neither effect is observed for tertiary phosphinophenolate/Ni polymerization catalysts.
