146380-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146380-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 146380-20:
(8*1)+(7*4)+(6*6)+(5*3)+(4*8)+(3*0)+(2*2)+(1*0)=123
123 % 10 = 3
So 146380-20-3 is a valid CAS Registry Number.

E- OR Z-SELECTIVE WITTIG REACTIONS IN THE SYNTHESIS OF THE CARBACYCLIN ILOPROST
Westermann, Juergen,Harre, Michael,Nickisch, Klaus
, p. 8055 - 8056 (2007/10/02)
Wittig reaction of ketones 3 with 4-carboxybutyltriphenyl-phosphonium bromide generates the exocyclic 5,6 double bond of iloprost (1) in E/Z ratios between 35:65 and 90:10 depending on substituents and reaction conditions.
