Check Digit Verification of cas no
The CAS Registry Mumber 129077-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,7 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129077-96:
(8*1)+(7*2)+(6*9)+(5*0)+(4*7)+(3*7)+(2*9)+(1*6)=149
149 % 10 = 9
So 129077-96-9 is a valid CAS Registry Number.

An asymmetric synthesis of L-[3-13C]phenylalanine and L-[3- 13C]tyrosine from [13C]carbon monoxide

, p. 15861 - 15869 (2007/10/03)
L-[3-13C]Phenylalanine and L-[3-13C]tyrosine were synthesized. [α- 13C]Benzyl bromides were prepared from [13C]carbon monoxide via the palladium-catalyzed carboalkoxylation of aryl halides. The asymmetric carbon corresponding to the 2-position in phenylalanine was introduced by the diastereoselective alkylation of Dellaria's oxazinone with [α-13C]benzyl bromides. Finally, ethanolysis, deprotection, hydrogenolysis and acid hydrolysis of the resulting alkylated oxazinones gave L-[3- 13C]phenylalanine and L-[3-13C]tyrosine in high optical purity.
