17357-38-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17357-38-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,5 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17357-38:
(7*1)+(6*7)+(5*3)+(4*5)+(3*7)+(2*3)+(1*8)=119
119 % 10 = 9
So 17357-38-9 is a valid CAS Registry Number.

Dess-Martin periodinane mediated synthesis of thioesters from aldehydes

Bandgar, Sunita B.,Bandgar,Korbad,Sawant

, p. 1287 - 1290 (2007)

Dess-Martin periodinane (DMP) mediated efficient synthesis of thioesters from the corresponding aldehydes under mild conditions is described.

Thioesterification and Selenoesterification of Amides via Selective N-C Cleavage at Room Temperature: N-C(O) to S/Se-C(O) Interconversion

Li, Guangchen,Rahman, Md. Mahbubur,Szostak, Michal

, p. 1060 - 1066 (2020/04/01)

The direct nucleophilic addition to amides represents an attractive methodology in organic synthesis that tackles amidic resonance by ground-state destabilization. This approach has been recently accomplished with carbon, nitrogen and oxygen nucleophiles.

Imidazolium-supported benzotriazole: an efficient and recoverable activating reagent for amide, ester and thioester bond formation in water

Shakoor, S.M. Abdul,Choudhary, Sunita,Bajaj, Kiran,Muthyala, Manoj Kumar,Kumar, Anil,Sakhuja, Rajeev

, p. 82199 - 82207 (2015/10/12)

An efficient and recyclable imidazolium-supported benzotriazole reagent (Im-CH2-BtH) as a novel synthetic auxiliary has been synthesized and its utility as a carboxyl group activating reagent via the formation of stable imidazolium-supported acyl benzotriazoles was explored for the synthesis of amides, esters and thioesters in water under microwave conditions. The reagent was reused five times without any noticeable loss in activity. It is moisture insensitive and highly stable under thermal and aerobic conditions. The application of imidazolium-supported N-acetyl benzotriazole leads to synthesis of paracetamol on the gram scale under greener conditions in 93% yield.
