Check Digit Verification of cas no
The CAS Registry Mumber 100643-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,6,4 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100643-25:
(8*1)+(7*0)+(6*0)+(5*6)+(4*4)+(3*3)+(2*2)+(1*5)=72
72 % 10 = 2
So 100643-25-2 is a valid CAS Registry Number.

Combined matrix-isolation FT-IR and ab initio 6-31++G** study of H-bonded complexes between water and molecules modelling cytosine or isocytosine
Smets, Johan,Adamovicz, Ludwik,Maes, Guido
, p. 113 - 130 (1994)
A step-by-step experimental and ab initio SCF/6-31++G** procedure is described for the interpretation of the matrix FT-IR spectra of H-bonded complexes of cytosine or isocytosine with water.The method involves a detailed study of several compounds, each modelling one or a few cytosine sites and/or tautomers in order of increasing complexity.Results are presented for tautomerization processes in 2-OH-pyridine, 4-OH-pyrimidine and isocytosine, and for H-bonded complexes of water with pyrimidine, 4-OH-pyridine and 4-NH2-pyridine.The whole series of obtained results has allowed the setting up of a large-scale vibration correlation diagram for water complexed with N- and O-bases.It also allows some new, important conclusions to be drawn about the major problem of scaling ab initio predicted frequencies for anharmonic proton-donor vibrational modes.
