1759-00-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1759-00-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1759-00:
(6*1)+(5*7)+(4*5)+(3*9)+(2*0)+(1*0)=88
88 % 10 = 8
So 1759-00-8 is a valid CAS Registry Number.

Potassium Phosphate-Catalyzed Chemoselective Reduction of α-Keto Amides: Route to Synthesize Passerini Adducts and 3-Phenyloxindoles

Muthukumar, Alagesan,Mamillapalli, N. Chary,Sekar, Govindasamy

, p. 643 - 652 (2016/02/27)

A chemoselective reduction of α-keto amides to biologically important α-hydroxy amides (mandelamides) by polymethylhydrosiloxane (PMHS) using 5 mol% potassium phosphate (K3PO4) as catalyst has been developed. This transition metal-free protocol discloses excellent chemoselectivity for the ketone reduction of α-keto amides in the presence of other reducible functionalities like ketone, nitro, halides, nitrile and amide. Also, the chemoselectively reduced α-hydroxy amide has been derivatized to isocyanide-free Passerini adducts. The N-alkyl-α-hydroxy amides have been successfully converted to 3-phenyloxindole derivatives by treatment with methanesulfonyl cholride and triethylamine.
