Check Digit Verification of cas no
The CAS Registry Mumber 7301-93-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7301-93:
(6*7)+(5*3)+(4*0)+(3*1)+(2*9)+(1*3)=81
81 % 10 = 1
So 7301-93-1 is a valid CAS Registry Number.

PREPARATION DE SELS D'AMINOALKYLPHOSPHONIUMS
Dantas, T. N. de Castro,Laval, J. P.,Lattes, A.
, p. 97 - 106 (2007/10/02)
Three synthetic methods have been applied to prepare amino phosphonium salts: (C6H5)3P+-(CH2)n-N-.The best ways have been determined for different n values and different substituents on the nitrogen atom.In all cases, yields are better with n=3, but no intramolecular stabilization has been detected.
