1215940-03-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1215940-03-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,9,4 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1215940-03:
(9*1)+(8*2)+(7*1)+(6*5)+(5*9)+(4*4)+(3*0)+(2*0)+(1*3)=126
126 % 10 = 6
So 1215940-03-6 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

, p. 367 - 371 (2012)

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.
