Check Digit Verification of cas no
The CAS Registry Mumber 81478-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,7 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81478-17:
(7*8)+(6*1)+(5*4)+(4*7)+(3*8)+(2*1)+(1*7)=143
143 % 10 = 3
So 81478-17-3 is a valid CAS Registry Number.

Paragraph 0025; 0026; 0044; 0045; 0063; 0064, (2017/09/13)
The invention discloses a preparation method of methyl 4-amino-2-(2-ethylamino)butyrate dihydrochloride. The methyl 4-amino-2-(2-ethylamino)butyrate dihydrochloride is prepared from tetrahydropyran-4-carboxylic acid used as an initial raw material through a ring opening bromination lactone formation ring, a hydrolysis reaction, a Ts reaction on a hydroxyl group, a methyl esterification reaction, an azidation reaction and a hydrogenation reduction reaction. The process route is slightly long, but the yield of every step approaches a theoretic yield, and azide can be purified only through one step; and the preparation method also has the advantages of small polarity and easy purification of the azide, convenience in operation, mild and easily-controlled reaction conditions, and low cost.
