Check Digit Verification of cas no
The CAS Registry Mumber 105163-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,1,6 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105163-75:
(8*1)+(7*0)+(6*5)+(5*1)+(4*6)+(3*3)+(2*7)+(1*5)=95
95 % 10 = 5
So 105163-75-5 is a valid CAS Registry Number.

2-(4-Pyridyl)ethyl as a Protective Group for Sulfur Functionality
Katritzky, Alan R.,Takahashi, Ichiro,Marson, Charles M.
, p. 4914 - 4920 (2007/10/02)
2-(4-Pyridyl)ethyl sulfides have been prepared from a variety of alkyl and aryl thiols and from alkyl and acyl halides.These sulfides and their corresponding sulfoxides and sulfones were each depyridylethylated by quaternization and subsequent treatment with mild base to give respectively the thiols, sulfenic acids, sulfinic acids, and sulfenamides.During one of these protection-deprotection sequences, methyl 1-octyl sulfoxide was readily converted by aerial oxidation into the corresponding sulfone.
