445411-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 445411-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,4,1 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 445411-98:
(8*4)+(7*4)+(6*5)+(5*4)+(4*1)+(3*1)+(2*9)+(1*8)=143
143 % 10 = 3
So 445411-98-3 is a valid CAS Registry Number.

Synthesis of novel azaxanthones derived from N-hydroxyazoles
Kristensen, Jesper L,Veds?, Per,Begtrup, Mikael
, p. 2397 - 2404 (2007/10/03)
The synthesis of a new class of azaxanthones is presented. The N-O functionality of 1-hydroxypyrazole and 1-hydroxy-1,2,3-triazole was used to direct metalation and subsequently in the new ring systems.
