Check Digit Verification of cas no

The CAS Registry Mumber 34998-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,9 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34998-70:
(7*3)+(6*4)+(5*9)+(4*9)+(3*8)+(2*7)+(1*0)=164
164 % 10 = 4
So 34998-70-4 is a valid CAS Registry Number.

Platinum-catalyzed oxoarylations of ynamides with nitrones

Bhunia, Sabyasachi,Chang, Chin-Jung,Liu, Rai-Shung

supporting information, p. 5522 - 5525,4 (2020/10/15)

A new platinum-catalyzed oxoarylation of ynamides with nitrones is reported. Cascade sequences for the synthesis of indolin-2-ones via NaBH 3CN reduction in situ of the initially formed oxoarylation products are also developed.

Microwave-assisted sequential amide bond formation and intramolecular amidation: A rapid entry to functionalized oxindoles

Poondra, Rajamohan R.,Turner, Nicholas J.

, p. 863 - 866 (2007/10/03)

(Chemical Equation Presented) A general method has been developed for the synthesis of N-substituted oxindoles. The two-step process involves initial microwave-assisted amide bond formation between 2-halo-arylacetic acids and various alkylamines and anilines, followed by a palladium-catalyzed intramolecular amidation under aqueous conditions. In the case of alkylamines, the procedure can be carried out as a one-pot process without isolation of the intermediate amide.
