131573-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131573-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,7 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131573-40:
(8*1)+(7*3)+(6*1)+(5*5)+(4*7)+(3*3)+(2*4)+(1*0)=105
105 % 10 = 5
So 131573-40-5 is a valid CAS Registry Number.

Pure Enantiomers from Retro-Diels-Alder Processes
Beckmann, Marion,Hildebrandt, Hinrich,Winterfeldt, Ekkehard
, p. 335 - 345 (2007/10/02)
Diastereoselective and regioselective transformations of cycloadducts to enantiomerically pure cyclopentadienes are reported.Retro-Diels-Alder processes finally give rise to pure enantiomers in high yield.
