Check Digit Verification of cas no

The CAS Registry Mumber 79240-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,4 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 79240-31:
(7*7)+(6*9)+(5*2)+(4*4)+(3*0)+(2*3)+(1*1)=136
136 % 10 = 6
So 79240-31-6 is a valid CAS Registry Number.

THE pH DEPENDENCE OF PHENOLPHTHALEIN; A (13)C NMR STUDY

Berger, Stefan

, p. 1607 - 1612 (1981)

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.
