140199-82-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140199-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,9 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140199-82:
(8*1)+(7*4)+(6*0)+(5*1)+(4*9)+(3*9)+(2*8)+(1*2)=122
122 % 10 = 2
So 140199-82-2 is a valid CAS Registry Number.

Spontaneous dissociation of phosphoniumylidyl-chlorophosphines to ionic phosphenium chlorides
Schmidpeter, Alfred,Jochem, Georg
, p. 471 - 474 (2007/10/02)
The products from the replacement of two chlorofunctions of PCl3 by a pair of phosphoniumylidyl substituents or by both a phosphoniumylidyl and an amino substituent are ionic phosphenium chlorides and not covalent chlorophosphines.
