Check Digit Verification of cas no
The CAS Registry Mumber 303991-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,9,9 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 303991-53:
(8*3)+(7*0)+(6*3)+(5*9)+(4*9)+(3*1)+(2*5)+(1*3)=139
139 % 10 = 9
So 303991-53-9 is a valid CAS Registry Number.

Palladium-catalyzed C-C coupling of aryl halides with isocyanides: An alternative method for the stereoselective synthesis of (3E)-(Imino)isoindolin- 1-ones and (3E)-(imino)thiaisoindoline 1,1-dioxides

A palladium-catalyzed, one-pot cyclization reaction to construct (3E)-(imino)isoindolin-1-ones and (3E)-(imino)thiaisoindoline 1,1-dioxides by introducing ortho-reactive functional groups on aryl halides is reported. Under optimal conditions, the cyclization reaction afforded the corresponding products in good to excellent yields (up to 93%) with high stereoselectivity. Notably, this transformation successfully extends its application for the synthesis of phenanthridines and dibenzooxazepines. This new synthetic protocol not only extends the application platform for palladium-catalyzed C-C coupling of aryl halides with isocyanides, but also opens atom-economic and step-economic synthetic routes for nitrogen-containing heterocyclic compounds with wide functional group compatibility.
