244109-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244109-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,1,0 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 244109-46:
(8*2)+(7*4)+(6*4)+(5*1)+(4*0)+(3*9)+(2*4)+(1*6)=114
114 % 10 = 4
So 244109-46-4 is a valid CAS Registry Number.

Simple and practical routes to enantiomerically pure 5-(Trialkylsilyl)-2-cyclohexenones
Sarakinos, Georgios,Corey
, p. 811 - 814 (2008/02/12)
Formula presented Enantiomerically pure chiral 5-silylated 2-cyclohexenones are easily prepared in high yield using as a key step kinetic resolution with a commercially available lipase. Fully active enzyme can be recovered very efficiently for reuse. The
