Check Digit Verification of cas no

The CAS Registry Mumber 1449299-44-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,2,9 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1449299-44:
(9*1)+(8*4)+(7*4)+(6*9)+(5*2)+(4*9)+(3*9)+(2*4)+(1*4)=208
208 % 10 = 8
So 1449299-44-8 is a valid CAS Registry Number.

Stereoselective synthesis of β-alkylated α-amino acids via palladium-catalyzed alkylation of unactivated methylene C(sp3)-H Bonds with Primary Alkyl Halides

Zhang, Shu-Yu,Li, Qiong,He, Gang,Nack, William A.,Chen, Gong

, p. 12135 - 12141 (2013/09/02)

We report a new set of reactions based on the Pd-catalyzed alkylation of methylene C(sp3)-H bonds of aliphatic quinolyl carboxamides with α-haloacetate and methyl iodide and applications in the stereoselective synthesis of various β-alkylated α-amino acids. These reactions represent the first generally applicable method for the catalytic alkylation of unconstrained and unactivated methylene C-H bonds with high synthetic relevance. When applied with simple isotope-enriched reagents, they also provide a convenient and powerful means to site-selectively incorporate isotopes into the carbon scaffolds of amino acid compounds.
