190326-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190326-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,3,2 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190326-36:
(8*1)+(7*9)+(6*0)+(5*3)+(4*2)+(3*6)+(2*3)+(1*6)=124
124 % 10 = 4
So 190326-36-4 is a valid CAS Registry Number.

Synthesis of linear dimeric and cyclic oligomeric cholate ester derivatives
Li, Yuexian,Dias, Jerry Ray
, p. 425 - 430 (2007/10/03)
One-step syntheses of cyclic trimer 2 and tetramer 3 of lithocholate were achieved from the cycloesterification of lithocholic acid (1) by using 2-chlorobenzoyl chloride and 4-dimethylaminopyridine (DMAP). The tetramer 5 of 7,12-diacetyl-24-norcholic acid
