Check Digit Verification of cas no

The CAS Registry Mumber 17419-98-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,4,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17419-98:
(7*1)+(6*7)+(5*4)+(4*1)+(3*9)+(2*9)+(1*8)=126
126 % 10 = 6
So 17419-98-6 is a valid CAS Registry Number.

Synthesis of six-membered cyclic sulfonimidamides

Sen, Indira,Kloer, Daniel,Hall, Roger,Pal, Sitaram

, p. 3018 - 3028 (2013/11/06)

A general synthetic route to six-membered cyclic N-aryl- and N-alkyl-substituted sulfonimidamides via an intramolecular ring closure of suitably functionalised acyclic sulfonimidamides is described. The structure of this new ring system was confirmed by v

Substituted N-aryl alk-1-enesulfinamides: Preparation, properties and conversion into the corresponding indole compounds [1]

Baudin, Jean-Bernard,Commenil, Marie-Gabrielle,Julia, Sylvestre A.,Lorne, Robert,Mauclaire, Laurent

, p. 329 - 350 (2007/10/03)

Reaction of vinylic organometallic derivatives with N-sulfinyl arenamines 2 affords the title sulfinamides 3. On heating their solutions in selected solvents to 80-124 °C, these sulfinamides are converted into the corresponding indoles 6, probably via a [3.3]-sigmatropic rearrangement to intermediates VIII which undergo an intramolecular carbophilic reaction of the nitrogen atom with the neighboring sulfine group, followed by elimination of HSOH. The triethyloxonium tetrafluoroborate- or boron trifluoride etherate catalyzed conversion 3 → 6 can be carried out at a much lower temperature. Elsevier,.
