Check Digit Verification of cas no
The CAS Registry Mumber 219297-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,2,9 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 219297-09:
(8*2)+(7*1)+(6*9)+(5*2)+(4*9)+(3*7)+(2*0)+(1*9)=153
153 % 10 = 3
So 219297-09-3 is a valid CAS Registry Number.

Paragraph 0032; 0033; 0034; 0035; 0037; 0043, (2017/08/28)
The invention relates to a synthesis method of chiral N-Boc-3-amino-4-aryl-butyric acid. The method is as below: 1, conducting a cross metathesis reaction, an asymmetric conjugate addition reaction and an oxidation reaction on starting materials including an allyl aromatic compound and crotonaldehyde by a continuous reaction one-pot method to synthesize an N-Boc-3-aryl methyl-5-oxo isoxazole intermediate; or conducting an asymmetric conjugate addition reaction and an oxidation reaction on a starting material (E)-4-aryl-2-crotonaldehyde by a continuous reaction one-pot method to synthesize an N-Boc-3-aryl methyl-5-oxo isoxazole intermediate; and 2, subjecting (3R)-N-Boc-3-aryl methyl-5-oxo isoxazole intermediate by high-pressure hydrogenation to directly prepare the chiral N-Boc-3-amino-4-aryl-butyric acid. The synthesis method provided by the invention has the advantages of simple operation, mild reaction conditions, target product yield reaching 60-69%, and ee value of the target product reaching as high as 96%. The synthetic route has industrialization prospect.
