The CAS Registry Mumber 121731-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121731-89:
(8*1)+(7*2)+(6*1)+(5*7)+(4*3)+(3*1)+(2*8)+(1*9)=103
103 % 10 = 3
So 121731-89-3 is a valid CAS Registry Number.

Functionalization of Phenyl Rings by Imidoylnitrenes

Dabbagh, Hossein A.,Lwowski, Walter

, p. 3952 - 3957 (1989)

The electrophilic reactivity of imidoylnitrenes ROC(=NZ)N can be controlled by the choice of Z.With Z = SO2CH3, benzenes react only if they bear electron-donating substituents.The resulting N-arylisoureas, ROC(=NZ)NHAr, can be obtained conveniently and in
