117635-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117635-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,3 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117635-25:
(8*1)+(7*1)+(6*7)+(5*6)+(4*3)+(3*5)+(2*2)+(1*5)=123
123 % 10 = 3
So 117635-25-3 is a valid CAS Registry Number.

A High-Yield Route to 2,5-Di-n-alkyl-1,4-benzenedicarboxylic Acids
Rehahn, Matthias,Schlueter, Arnulf-Dieter,Feast, W. James
, p. 386 - 388 (2007/10/02)
A simple and inexpensive method for preparing the previously unknown 2,5-di-n-alkylterephthalic acids 5a-d in high yields is presented.The length of the alkyl chains can be varied easily (n=6,8,12,16).
