63670-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63670-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,6,7 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63670-13:
(7*6)+(6*3)+(5*6)+(4*7)+(3*0)+(2*1)+(1*3)=123
123 % 10 = 3
So 63670-13-3 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,
