33376-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33376-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,7 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33376-25:
(7*3)+(6*3)+(5*3)+(4*7)+(3*6)+(2*2)+(1*5)=109
109 % 10 = 9
So 33376-25-9 is a valid CAS Registry Number.

Synthesis and reactions of some N-mono- and N,N'-bis-salicyloyl derivatives of barbituric acid
Sladowska
, p. 447 - 456 (2007/10/02)
N,N'-Bis-salicyloyl derivatives unlike the N-mono-salicyloyl derivatives of barbituric acid underwent thermal decomposition. The decomposition products depend on the size of the substituents in the position 5. When one of them is phenyl, salicyloyl radicals are split off without cleavage of the barbituric ring.
