83283-98-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83283-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,8 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83283-98:
(7*8)+(6*3)+(5*2)+(4*8)+(3*3)+(2*9)+(1*8)=151
151 % 10 = 1
So 83283-98-1 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
