73893-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73893-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,9 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73893-81:
(7*7)+(6*3)+(5*8)+(4*9)+(3*3)+(2*8)+(1*1)=169
169 % 10 = 9
So 73893-81-9 is a valid CAS Registry Number.

Opening of the Furan Ring in 5-Azido-2-furaldehyde
Povazanec, Frantisek,Kovac, Jaroslav,Hesek, Dusan
, p. 150 - 154 (2007/10/02)
Fission of the furan ring in 5-azido-2-furaldehyde is described. α-Furylnitrene, formed from α-azido furan derivatives, is stabilized by the furan ring fission.Transformation of the intermediate to quinoxaline and pyrazole derivatives is also studied.
