189871-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189871-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,7 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189871-18:
(8*1)+(7*8)+(6*9)+(5*8)+(4*7)+(3*1)+(2*1)+(1*8)=199
199 % 10 = 9
So 189871-18-9 is a valid CAS Registry Number.

Asymmetric synthesis and absolute stereochemistry of 4,4-bis(trifluoromethyl)imidazoline based ACAT inhibitors
Li, Hui-Yin,DeLucca, Indawati,Drummond, Spencer,Boswell, George A.
, p. 5359 - 5372 (2007/10/03)
An asymmetric synthesis of 1, a potent orally active ACAT inhibitor, is reported. The absolute configuration of 1 has been determined by exciton CD spectra and X-ray crystal structure analysis.
