7511-58-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7511-58-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,1 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7511-58:
(6*7)+(5*5)+(4*1)+(3*1)+(2*5)+(1*8)=92
92 % 10 = 2
So 7511-58-2 is a valid CAS Registry Number.

4-Benzoylamino-3-hydroxybutyric acid, historically first "anomalous racemate": Reinvestigation

Bredikhin, Alexander A.,Bredikhina, Zemfira A.,Zakharychev, Dmitry V.,Samigullina, Aida I.,Gubaidullin, Aidar T.

, p. 1362 - 1373 (2015/05/20)

Chiral 4-benzoylamino-3-hydroxybutyric acid (1) was recognized in 1930 as the first example of "anomalous racemates" (correct to say, anomalous conglomerates), that is, specific addition compounds formed by different enantiomers in unequal ratio. Through the comparative (racemic against homochiral samples) inspection of the IR spectra, single crystal X-ray diffraction, PXRD analysis, and solubility data we have found that this substance forms normal racemic compound in the solid state, and must be excluded from the very short list of anomalous conglomerates. At the same time homo-1 is dissolved in 25 times better than rac-1, and this feature belongs to another interesting and rare type, namely, "anticonglomerates". Some of the reasons for this behavior are discussed.
