228702-96-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228702-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,7,0 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 228702-96:
(8*2)+(7*2)+(6*8)+(5*7)+(4*0)+(3*2)+(2*9)+(1*6)=143
143 % 10 = 3
So 228702-96-3 is a valid CAS Registry Number.

, p. 855 - 862 (2007/10/03)
Enantiomerically pure (4R,5R)- and (4S,5S)-2-imidazolines 5 were conveniently obtained on a gram scale. These can be converted into enantiopure (2R,3R)-2,3-diamino ester 6 or 2,3-diamino alcohol 7 by hydrolysis or reduction.
