885517-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 885517-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,5,1 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 885517-59:
(8*8)+(7*8)+(6*5)+(5*5)+(4*1)+(3*7)+(2*5)+(1*9)=219
219 % 10 = 9
So 885517-59-9 is a valid CAS Registry Number.

An efficient and odorless synthesis of thioethers using 2-[Bis(alkylthio)methylene]-3-oxo-N-o-tolylbutanamides as thiol equivalents

Yu, Haifeng

scheme or table, p. 367 - 371 (2012/04/23)

Using 2-[bis(alkylthio)methylene]-3-oxo-N-o-tolylbutanamides 1 as odorless thiol equivalents, an efficient and odorless synthesis of thioethers has been developed. Promoted by NaOH in EtOH, the cleavage of 1 commences to generate thiolate anions, and the generated thiolate anions then react with halides to give various thioethers in good yield. It is noteworthy that only a very faint odor of thiols can be perceived during both the reaction and the workup.
