434321-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 434321-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,4,3,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 434321-76:
(8*4)+(7*3)+(6*4)+(5*3)+(4*2)+(3*1)+(2*7)+(1*6)=123
123 % 10 = 3
So 434321-76-3 is a valid CAS Registry Number.

Sase, Shohei,Kano, Naokazu,Kawashima, Takayuki
, p. 268 - 269 (2002)
The phosphonium cations bearing the Martin ligand abstracted a fluoride ion from their counter anion, tetrafluoroborate, and the corresponding fluorophosphoranes were obtained in good yields.
