79448-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79448-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,4 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 79448-85:
(7*7)+(6*9)+(5*4)+(4*4)+(3*8)+(2*8)+(1*5)=184
184 % 10 = 4
So 79448-85-4 is a valid CAS Registry Number.

THE pH DEPENDENCE OF PHENOLPHTHALEIN; A (13)C NMR STUDY
Berger, Stefan
, p. 1607 - 1612 (2007/10/02)
The pH dependence of the (13)C NMR spectra of phenolphthalein has been measured and interpreted.The spectrum of the neutral compound 1 is compared with the spectra of the dianion 4, the trianion 5 and the carbocation 7.At the first time spectroscopic evidence for the carbinol 6 is given.
