141331-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141331-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,3,3 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141331-13:
(8*1)+(7*4)+(6*1)+(5*3)+(4*3)+(3*1)+(2*1)+(1*3)=77
77 % 10 = 7
So 141331-13-7 is a valid CAS Registry Number.

Carbohydrates as chiral templates: Stereoselective synthesis of (R)- and (S)-α-aminophosphonic acid derivatives
Laschat,Kunz
, p. 90 - 95 (2007/10/02)
The stereoselective synthesis of diethyl (S)- or (R)-α-[(O-pivaloyl-hexapyranosyl)amino]benzylphosphonates is achieved via Lewis acid catalyzed addition of diethyl phosphite to O-pivaloylated N-benzylidene-β-D-galactosylamine or N-benzylidene-α-D-arabinop
