871331-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871331-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,3,3 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 871331-03:
(8*8)+(7*7)+(6*1)+(5*3)+(4*3)+(3*1)+(2*0)+(1*3)=152
152 % 10 = 2
So 871331-03-2 is a valid CAS Registry Number.

Enantioselective synthesis of β-amino-diacids
Alladoum, Jeanne,Dechoux, Luc
, p. 8203 - 8205 (2007/10/03)
An efficient route to orthogonally protected β-amino-diacids is described: chiral derivative 3 was shown to be a precursor of enantiopure substituted β-amino acids. The key step of the procedure is a diastereoselective reduction of β-enaminolactones 5 by
