17675-89-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17675-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17675-89:
(7*1)+(6*7)+(5*6)+(4*7)+(3*5)+(2*8)+(1*9)=147
147 % 10 = 7
So 17675-89-7 is a valid CAS Registry Number.

A Scalable Process for the Synthesis of 1,2-Dialkyldiselanes and 1-Alkaneselenols

Cooksey, John P.,Kocieński, Philip J.,Blacker, A. John

supporting information, p. 2571 - 2575 (2019/11/14)

A four-step telescoped process for the synthesis of 1-alkaneselenols entails (1) the rapid formation of potassium selenocyanate from potassium cyanide and selenium in methanol, (2) the nucleophilic substitution of bromoalkanes or alkyl tosylates with potassium selenocyanate, (3) the mild base-catalyzed conversion of the resultant 1-alkaneselenocyanates to 1,2-dialkyldiselanes (the Krief reaction), and (4) the reduction of the resultant 1,2-dialkyldiselanes with hypophosphorous acid to give the desired 1-alkaneselenols. The process has been used to produce 1-octaneselenol on a 10.4 mol scale. Nine examples of the process are described.

Synthesis of primary-alkyl selenols and selenides from primary-alkyl thiols involving diphenyl sulfonium salts

Krief, Alain,Dumont, Willy,Robert, Michael

, p. 2167 - 2168 (2007/10/03)

Hexyl thiol has been transformed to hexyl selenol and related selenides and selenocyanate by substitution of the corresponding hexyldiphenylsulfonium tetrafluoroborate with selenium nucleophiles. The Royal Society of Chemistry 2005.
