129119-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129119-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,1 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129119-99:
(8*1)+(7*2)+(6*9)+(5*1)+(4*1)+(3*9)+(2*9)+(1*9)=139
139 % 10 = 9
So 129119-99-9 is a valid CAS Registry Number.

Stereoselective syntheses of fluorescent non-natural aromatic amino acids based on asymmetric michael additions
Chen, Heru,Zhong, Xianbin,Wei, Jin
, p. 1170 - 1182 (2008/02/05)
Four fluorescent non-natural aromatic amino acids have been synthesized based on a key stereoselective Michael addition reaction. S-1-Phenylethylamine was employed as both the source of amine and the stereoselectivity controller. The overall yields were m
