Check Digit Verification of cas no

The CAS Registry Mumber 11121-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,1,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 11121-17:
(7*1)+(6*1)+(5*1)+(4*2)+(3*1)+(2*1)+(1*7)=38
38 % 10 = 8
So 11121-17-8 is a valid CAS Registry Number.

Homogeneous borotungstic acid (cas 11121-17-8) and heterogeneous micellar borotungstic acid (cas 11121-17-8) catalysts for biodiesel production by esterification of free fatty acid07/19/2019

A highly negatively charged borotungstic acid H5BW12O40 had been tested as homogeneous catalyst in esterification. Compared with common used H3PW12O40, it displayed a higher conversion (98.7%) and excellent efficiency (96.2%) due to its high amount of protons in methanol. In order to overcome th...detailed
