90139-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90139-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,3 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90139-53:
(7*9)+(6*0)+(5*1)+(4*3)+(3*9)+(2*5)+(1*3)=120
120 % 10 = 0
So 90139-53-0 is a valid CAS Registry Number.

Page/Page column 9, (2008/06/13)
A method for carrying out a chemical reaction between at least two reactants occupying separate phases within a multiphase reaction mixture has been discovered in which at least one phosphazenium salt is employed as a phase transfer catalyst. The remarkab
