39604-15-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39604-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,6,0 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39604-15:
(7*3)+(6*9)+(5*6)+(4*0)+(3*4)+(2*1)+(1*5)=124
124 % 10 = 4
So 39604-15-4 is a valid CAS Registry Number.

Tf2O-Promoted Activating Strategy of Phosphate Analogues: Synthesis of Mixed Phosphates and Phosphinate

Huang, Hai,Ash, Jeffrey,Kang, Jun Yong

supporting information, p. 4938 - 4941 (2018/08/24)

A metal-, toxic chloride reagent-free activating strategy of various phosphates has been developed. This method enables the facile synthesis of functional phosphates such as alkyl phosphates, aza phosphates, thiophosphate, and mixed diaryl phosphates. A transient phosphorylpyridin-1-ium species in situ generated from phosphates with Tf2O/pyridine readily undergoes a substitution reaction with diverse nucleophiles to form versatile phosphate compounds.

New synthetic approach to (o-hydroxyphenyl)methylphosphonic acid derivatives

Consiglio, Giuseppe A.,Failla, Salvatore,Finocchiaro, Paolo

, p. 182 - 183 (2007/10/03)

2,6-Dimethylphenols and 5,5′-dimethyl-6,6′-spirobiindanol react with diethylphosphite to give phosphates, which are easily transformed by LDA to (o-hydroxyphenyl)methylphosphonates.
