73549-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73549-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,4 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73549-58:
(7*7)+(6*3)+(5*5)+(4*4)+(3*9)+(2*5)+(1*8)=153
153 % 10 = 3
So 73549-58-3 is a valid CAS Registry Number.

SYNTHESIS OF ISOMERIC 1,1'-PHENYLENE-BIS(6-AZAURACIL-5-CARBONITRILES)
Slouka, Jan
, p. 2967 - 2976 (2007/10/02)
The described synthesis of all three isomeric 1,1'-phenylenebis(6-azauracil-5-carbonitriles) IVa-IVc starts from the respective 1-nitrophenyl-6-azauracil-5-carbonitriles Ia-Ic which were reduced to the corresponding amino derivatives IIa-IIc, diazotized,
