Check Digit Verification of cas no
The CAS Registry Mumber 90474-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,7 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90474-60:
(7*9)+(6*0)+(5*4)+(4*7)+(3*4)+(2*6)+(1*0)=135
135 % 10 = 5
So 90474-60-5 is a valid CAS Registry Number.

Attempted Preparation of Sulfonioindenides
Hartke, Klaus,Schilling-Pindur, Annegret
, p. 552 - 563 (2007/10/02)
3-(Methylthio)indene (13), obtained from lithium 1-indenide (10) and dimethyl disulfide (11), reacts with methyl iodide to form truxene (14) and with methyl fluorosulfonate to form 2-(3-indenyl)-3-(methylthio)indene (16).Nucleophilic substitution of 1-chloro-2,3-dimethyl-5,6-(methylenedioxy)indene (22) with thiolates allows the isolation of the thioethers 23A/23B, which were alkylated with trialkyloxonium salts to give the stable sulfonium tetrafluoroborates 24.Deprotonation of 24 leads to extensive decomposition.The thioethers 28 have been prepared from 2-indanone (26).Their alkylation leads to the formation of (2-indenyl)sulfonium tetrafluoroborates 29.Deprotonation of 29a yields 2-(dimethylsulfonio)indenide (6), characterized by NMR spectroscopy.
