1037681-49-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1037681-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,7,6,8 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1037681-49:
(9*1)+(8*0)+(7*3)+(6*7)+(5*6)+(4*8)+(3*1)+(2*4)+(1*9)=154
154 % 10 = 4
So 1037681-49-4 is a valid CAS Registry Number.

Facile carbamoylation of 3,4-dihydropyridin-2-one with N-chlorosulfonyl isocyanate

Sa?ański, Piotr,Young, Kwan Ko,Lee, Kee-In

, p. 46 - 48 (2006)

3,4-Dihydro-2-pyridone-5-carboxylic acid amides were prepared by carbamoylation at the C-5 position of 3,4-dihydropyridin-2-one with N-chlorosulfonyl isocyanate.

Synthesis of Cyclic Imides by Acceptorless Dehydrogenative Coupling of Diols and Amines Catalyzed by a Manganese Pincer Complex

Espinosa-Jalapa, Noel Angel,Kumar, Amit,Leitus, Gregory,Diskin-Posner, Yael,Milstein, David

supporting information, p. 11722 - 11725 (2017/09/07)

The first example of base-metal-catalyzed dehydrogenative coupling of diols and amines to form cyclic imides is reported. The reaction is catalyzed by a pincer complex of the earth abundant manganese and forms hydrogen gas as the sole byproduct, making the overall process atom economical and environmentally benign.

Direct site-selective arylation of enamides via a decarboxylative cross-coupling reaction

Gigant, Nicolas,Chausset-Boissarie, La?titia,Gillaizeau, Isabelle

supporting information, p. 816 - 819 (2013/03/28)

An efficient Pd-catalyzed decarboxylative cross-coupling reaction of simple enamides was achieved. Depending on the choice of the nitrogen-protecting group, a site-selective synthesis of mono- or diarylated framework(s) was performed under mild conditions
