Check Digit Verification of cas no
The CAS Registry Mumber 21577-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,7 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21577-25:
(7*2)+(6*1)+(5*5)+(4*7)+(3*7)+(2*2)+(1*5)=103
103 % 10 = 3
So 21577-25-3 is a valid CAS Registry Number.

13C and 15N NMR spectra of aminobenzimidazoles in solution and in the solid state
Garcia, M. Angeles,Claramunt, Rosa M.,Solcan, Tomas,Milata, Viktor,Alkorta, Ibon,Elguero, Jose
body text, p. 100 - 104 (2010/01/16)
The 13C [hexadeutero-dimethylsulfoxide (DMSO-d6), hexamethyl-phosphoramide (HMPA)-d18 and solid-state] and 15N (solid-state) NMR spectra of six C-aminobenzimidazoles have been recorded. The tautomerism of 4(7)-aminobenzimidazoles and 5(6)- aminobenzimidazoles has been determined and compared with B3LYP/6-311++G(d,p) calculations confirming the clear predominance of the 4-amino tautomer and the slight preference for the 6-amino tautomer. GIAO-calculated absolute shieldings compare well with experimental chemical shifts. Copyright
