290369-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 290369-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,6 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 290369-84:
(8*2)+(7*9)+(6*0)+(5*3)+(4*6)+(3*9)+(2*8)+(1*4)=165
165 % 10 = 5
So 290369-84-5 is a valid CAS Registry Number.

Asymmetric synthesis of unusual amino acid: Synthesis of four isomers of β-methyl-3-(2'-naphthyl)alanine
Yuan, Wei,Hruby, Victor J.
, p. 3853 - 3856 (1997)
The synthesis of all four individual isomers of 3-methyl-3-(2'-naphthyl)analine was accomplished using asymmetric conjugate 1,4-addition followed by direct or indirect azidation using an Evans-type chiral auxiliary (4-phenyl-2-oxazolidinone).
