Check Digit Verification of cas no

The CAS Registry Mumber 82902-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,0 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82902-54:
(7*8)+(6*2)+(5*9)+(4*0)+(3*2)+(2*5)+(1*4)=133
133 % 10 = 3
So 82902-54-3 is a valid CAS Registry Number.

Catalytic N-Acylation of Cyclic Amines by Arylglyoxylic Acids via Radical-Radical Cross-Coupling

Bhadra, Sukalyan,Gupta, Aniket,Kumar Singh, Anupam,Rahaman, Ajijur

supporting information, p. 2198 - 2202 (2021/07/22)

A methodical mechanistic investigation allowed for the catalytic N-acylation of secondary cyclic amine counterparts by arylglyoxylic acids through radical-radical coupling. The reaction proceeds via a twofold SET-promoted Cu(I)/Cu(II) catalytic cycle under mild conditions. An analogous reaction variant allows for the N-acylation in a one-pot fashion directly starting from a secondary cyclic amine even in the presence of a second amine or hydroxy group.

Visible-Light-Mediated Efficient Metal-Free Catalyst for α-Oxygenation of Tertiary Amines to Amides

Zhang, Yu,Riemer, Daniel,Schilling, Waldemar,Kollmann, Jiri,Das, Shoubhik

, p. 6659 - 6664 (2018/06/25)

A metal-free system has been discovered for the efficient α-oxygenation of tertiary amines to the corresponding amides using oxygen as an oxidant. This visible-light-mediated oxygenation reaction exhibited excellent substrates scope under mild reaction conditions and generated water as the only byproduct. The synthetic utility of this approach has been demonstrated by applying onto drug molecules. At the end, detailed mechanistic reactions clearly showed the role of oxygen and the photocatalyst.

SeO2mediated efficient synthesis of amides and α-ketoamides of secondary amines with wide substrate scope

Meena, Samdarshi,Singh, Rohit,Vishwakarma, Ram A.,Aga, Mushtaq A.,Jain, Shreyans K.

supporting information, p. 3715 - 3717 (2016/07/26)

SeO2mediated oxidative amidation of acetophenones, phenylacetylenes, and phenylacetaldehydes to α-ketoamides and aldehydes to amides is reported. Amidation selectively proceeds with secondary amines. α-Ketoamide derivatives of natural products 16-dehydropregnenolone acetate (8), pregnenolone acetate (10), and progesterone (11) were synthesized.
