86508-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86508-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86508-31:
(7*8)+(6*6)+(5*5)+(4*0)+(3*8)+(2*3)+(1*1)=148
148 % 10 = 8
So 86508-31-8 is a valid CAS Registry Number.

Four syntheses A - D are described for the phosphonium salts 1, which are precursors of the highly reactive phosphoranes 3.Whereas the usual method B fails in some cases it is now possible to prepare 1 with a wide variety of substituents R1, R
