133568-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133568-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,6 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133568-70:
(8*1)+(7*3)+(6*3)+(5*5)+(4*6)+(3*8)+(2*7)+(1*0)=134
134 % 10 = 4
So 133568-70-4 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,
