Check Digit Verification of cas no
The CAS Registry Mumber 289712-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,7,1 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 289712-41:
(8*2)+(7*8)+(6*9)+(5*7)+(4*1)+(3*2)+(2*4)+(1*1)=180
180 % 10 = 0
So 289712-41-0 is a valid CAS Registry Number.

Preparation of 5-substituted 3-aminofuran-2-carboxylate esters.
Redman,Dumas,Scott
, p. 2061 - 2063 (2007/10/03)
[reaction: see text] An efficient method for the preparation of 3-aminofuran-2-carboxylate esters has been developed. This method is based on the reaction of an alpha-cyanoketone with ethyl glyoxylate under Mitsunobu conditions to produce a vinyl ether in
