52338-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52338-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,3,3 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52338-69:
(7*5)+(6*2)+(5*3)+(4*3)+(3*8)+(2*6)+(1*9)=119
119 % 10 = 9
So 52338-69-9 is a valid CAS Registry Number.

Trimethylsilylesters of Fluorobenzenesulfonic acids
Johannsen, Heiner,Sartori, Peter
, p. 674 - 679 (2007/10/02)
Fluorobenzenesulfonic acids were prepared by electrophilic sulfonation of fluorobenzenes 1.The acids are obtained as hydrates and converted to their trimethylsilyl esters 2 for characterization.
