Calculating the molecular weight, molecular mass and isotope pattern. The punctuations are not supported except "(",")","." and "-". One "-" indicates to minus one H2O from molecular formula. In that case, "-" can be showed in anywhere in the molecular formula. The following examples are correct.
CH3(CH2)9COOH (Click here to see Periodic Table. It will show all elements this software supports)
PhOH; MeOH; AcOEt (Click here to see groups which are supported by this software)
Gly-Ile-Ala-Thr-Asp; GlyIleAlaThrAsp----; AcO-Gly-Ile-Ala-Thr-Asp-COCH3 (Click here to see amino acids which are supported by this software)
Note: [13C] presents 13C(isotope); [19F] presents 19F(isotope)
