Check Digit Verification of cas no

The CAS Registry Mumber 117664-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,6 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117664-56:
(8*1)+(7*1)+(6*7)+(5*6)+(4*6)+(3*4)+(2*5)+(1*6)=139
139 % 10 = 9
So 117664-56-9 is a valid CAS Registry Number.

A catalysis study of mesoporous MCM-41 supported Schiff base and CuSO4·5H2O in a highly regioselective synthesis of 4-thiazolidinone derivatives from cyclocondensation of mercaptoacetic acid

, p. 335 - 339 (2016/03/16)

Mesoporous MCM-41 supported Schiff base and CuSO4·5H2O shows high catalytic activity in the cyclocondensation of mercaptoacetic acid with imines (or aldehydes and amines) to afford pharmaceutically important thiazolidinone derivatives. The catalytic reactions involving two-components or three-components afforded the desired product in high yields (up to 98% and 99%). Moreover, the catalyst works well with respect to recyclability, giving the product in 85% and 83% yields after recycling six times.
