Check Digit Verification of cas no
The CAS Registry Mumber 13967-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,6 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13967-65:
(7*1)+(6*3)+(5*9)+(4*6)+(3*7)+(2*6)+(1*5)=132
132 % 10 = 2
So 13967-65-2 is a valid CAS Registry Number.

Liquid-liquid solvent extraction of rare earths from chloride medium with sec-nonylphenoxy acetic acid and its mixtures with neutral organophosphorus extractants
Xiao, Pengfei,Bao, Changli,Song, Naizhong,Li, Cui,Jia, Qiong
, p. 1157 - 1161 (2011/10/18)
In the present study, sec-nonylphenoxy acetic acid (CA100) and its mixtures with four neutral organophosphorus extractants, tri-butyl-phosphate (TBP), 2-ethylhexyl phosphonic acid di-2-ethyl ester (DEHEHP), Cyanex923, and Cyanex925 have been applied to the extraction of rare earths. Results show that all the four mixing systems do not have evident synergistic effects on the extraction of rare earths. The different extraction effects have been considered to the separation of rare earths. The four mixtures may be applied to the separation of yttrium from some certain lanthanoids at proper mole fractions of CA100. Pleiades Publishing, Ltd., 2011.
