Check Digit Verification of cas no

The CAS Registry Mumber 175469-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,4,6 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 175469-62:
(8*1)+(7*7)+(6*5)+(5*4)+(4*6)+(3*9)+(2*6)+(1*2)=172
172 % 10 = 2
So 175469-62-2 is a valid CAS Registry Number.

Nitronium Ethyl Sulfate - A New Electrophilic Reagent. Stereochemistry of Addition across the C=C Bond

Zyk, N. V.,Lapin, Yu. A.,Nesterov, E. E.,Ugrak, B. I.,Zefirov, N. S.

, p. 777 - 787 (2007/10/03)

A new nitrating agent, nitronium ethyl sulfate, was prepared by reaction of ethyl nitrate with sulfuric anhydride.The agent has a ionic structure.New reactions of electrophilic addition of nitronium ethyl sulfate to a series of acyclic and mono-, bi-, and polycyclic alkenes, dienes, and trienes were studied; these reactions provide a synthetic approach to ethyl sulfate derivatives of nitro alcohols.The composition of the reaction products was analyzed in detail, and their structures were rigorously confirmed.Factors that govern the stoichiometry of addition and the directions of transformations of the carbon skeleton were revealed.
