Check Digit Verification of cas no

The CAS Registry Mumber 1238189-35-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,1,8 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1238189-35:
(9*1)+(8*2)+(7*3)+(6*8)+(5*1)+(4*8)+(3*9)+(2*3)+(1*5)=169
169 % 10 = 9
So 1238189-35-9 is a valid CAS Registry Number.

Polyether-substituted thiazolium ionic liquid catalysts - A thermoregulated phase-separable catalysis system for the Stetter reaction

Yu, Fengli,Zhang, Ruili,Xie, Congxia,Yu, Shitao

, p. 1196 - 1200 (2010)

A series of polyether-substituted thiazolium ionic liquids have been synthesized and used as catalysts in the Stetter reaction. The ionic liquids are a thermoregulated phase-separable catalysis (TPSC) system, because they possess the properties of critical solution temperature (CST) and inverse temperature-dependent solubility in toluene-heptane. The results showed that the novel TPSC system exhibits high recycling efficiency, and provides a potential route for a environmentally benign Stetter reaction. The Royal Society of Chemistry 2010.
