127643-98-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127643-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,4 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127643-98:
(8*1)+(7*2)+(6*7)+(5*6)+(4*4)+(3*3)+(2*9)+(1*8)=145
145 % 10 = 5
So 127643-98-5 is a valid CAS Registry Number.

Asymmetric synthesis of nonproteinogenic amino acids with l-amino acid transaminase: synthesis of (2S)-2-amino-4-oxo-4-phenylbutyric and (3E,2S)-2-amino-4-phenylbutenoic acids

Fadnavis, Nitin W.,Seo, Su-Hyun,Seo, Joo-Hyun,Kim, Byung-Gee

, p. 2199 - 2202 (2006)

2,4-Dioxo-4-phenylbutyric acid and 2-oxo-4-phenylbut-3-enoic acid are converted to the corresponding (S)-2-amino acids by recombinant Escherichia coli whole cells over-expressing aromatic transaminase from Enterobacter sp. BK2K-1 (AroATEs) in high yields (68-78%) and high enantiomeric purity (>99%) using l-aspartic acid as an amino donor.
