Check Digit Verification of cas no

The CAS Registry Mumber 96377-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,3,7 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 96377-82:
(7*9)+(6*6)+(5*3)+(4*7)+(3*7)+(2*8)+(1*2)=181
181 % 10 = 1
So 96377-82-1 is a valid CAS Registry Number.

Tetrakisphenol

Nowakowska,Daszkiewicz,Kyziol

, p. 1191 - 1197 (2007/10/03)

Formylation of bisphenol-A (1a), with subsequent methylation, oxidation and esterification, gave 2,2-bis-(4-methoxy-3-methoxycarbonylphenyl)-propane (11b). It was transformed into 2,2-bis-[4-methoxy-3-(2-hydroxy-2-propyl)-phenyl]-propane (12b) by the addition of methylmagnesium iodide. This carbinol was condensed with phenol in the presence of dry hydrogen chloride and the title compound was isolated as its tetramethyl ether (4b). Its structure of 2,2-bis-[4-hydroxy-3-(4-hydroxycumyl)-phenyl]-propane (4a) was confirmed by 13C-NMR spectra. In PhOH/HCl medium tetrakisphenol (4a) decomposed and isomerized to bisphenol-A (1a).
