200482-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200482-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,4,8 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 200482-55:
(8*2)+(7*0)+(6*0)+(5*4)+(4*8)+(3*2)+(2*5)+(1*5)=89
89 % 10 = 9
So 200482-55-9 is a valid CAS Registry Number.

The preparation of enantiomerically pure cyclopropylalanine
Boaz, Neil W.,Debenham, Sheryl D.,Large, Shannon E.,Moore, Mary K.
, p. 3575 - 3580 (2003)
Single enantiomer cyclopropylalanine (>99.9% ee) and various derivatives were prepared using an asymmetric hydrogenation approach with a rhodium catalyst based on the methyl BoPhoz ligand. N-Boc cyclopropylalanine benzyl ester was the preferred derivative
