145124-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145124-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,2 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145124-55:
(8*1)+(7*4)+(6*5)+(5*1)+(4*2)+(3*4)+(2*5)+(1*5)=106
106 % 10 = 6
So 145124-55-6 is a valid CAS Registry Number.

The synthesis of (+)- and (-)-flesinoxan: Application of enzymatic resolution methodology
Ennis,Ghazal
, p. 6287 - 6290 (1992)
The synthesis of (±)-flesinoxan was carried out in seven steps starting from catechol. An enzymatic resolution was utilized to prepare each enantiomer. Based upon the known preferences of the enzyme system used, we have assigned the (R)-configuration to the (+)-flesinoxan isomer.
