132540-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132540-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,4 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132540-69:
(8*1)+(7*3)+(6*2)+(5*5)+(4*4)+(3*0)+(2*6)+(1*9)=103
103 % 10 = 3
So 132540-69-3 is a valid CAS Registry Number.

Efficient EPC Synthesis of β-Aminobutanoic Acid
Gmeiner, Peter
, p. 501 - 502 (2007/10/02)
A practical approach to enantiomerically pure (R)-3-aminobutanoic acid (6) from L-asparagine is presented.The key step of the synthesis is the chemoselective reduction of the β-homoserine derivative 2.
