427899-56-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 427899-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,7,8,9 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 427899-56:
(8*4)+(7*2)+(6*7)+(5*8)+(4*9)+(3*9)+(2*5)+(1*6)=207
207 % 10 = 7
So 427899-56-7 is a valid CAS Registry Number.

Development of efficient processes for the preparation of Di-tert-butyl potassium phosphate and Di-tert-butyl (Chloromethyl) phosphate

Zheng, Bin,Fox, Richard J.,Sugiyama, Masano,Fritz, Alan,Eastgate, Martin D.

supporting information, p. 636 - 642 (2014/06/09)

A new and efficient process to prepare di-tert-butyl (chloromethyl) phosphate, a key compound in the formation of many phosphon-oxymethyl pro-drugs, from chloromethyl chlorosulfate (CMCS) and di-tert-butyl potassium phosphate (DTBPP) is described. To develop a process to this important compound with overall efficiency, an improved synthesis of DTBPP was required. The two-step process to DTBPP starts from PCl3 and leverages a H2O 2/catalytic KI mediated oxidation of di-tert-butyl phosphite to provide DTBPP in 81% yield and high purity. In the development of the new process to di-tert-butyl (chloromethyl) phosphate, a comparison to the corresponding tosylate derivative was made. A rational selection of base, phase-transfer catalyst (PTC), and stabilizing additive minimized CMCS decomposition and led to an optimized yield (90% solution yield), improved product purity, and identification of a technique to enable the long-term storage of di-tert-butyl (chloromethyl) phosphate.
