121928-30-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121928-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,2 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121928-30:
(8*1)+(7*2)+(6*1)+(5*9)+(4*2)+(3*8)+(2*3)+(1*0)=111
111 % 10 = 1
So 121928-30-1 is a valid CAS Registry Number.

2-AMINO-SUBSTITUTED DERIVATIVES OF BENZIMIDAZOLES FROM 2-ISOTHIOCYANATO CARBOXYLATES
Floch, Lubomir,Uher, Michal,Lesko, Jan
, p. 206 - 214 (2007/10/02)
2-isothiocyanato carboxylates react with o-phenylenediamine to give N,N'-substituted thioureas, which cyclize to yield 2-amino-substituted derivatives of imidazole.The structure of these compounds was corroborated by IR, UV, 1H, 13C NMR, and mass spectral
