109900-48-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109900-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,0 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109900-48:
(8*1)+(7*0)+(6*9)+(5*9)+(4*0)+(3*0)+(2*4)+(1*8)=123
123 % 10 = 3
So 109900-48-3 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.
