Check Digit Verification of cas no

The CAS Registry Mumber 1056157-47-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,6,1,5 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1056157-47:
(9*1)+(8*0)+(7*5)+(6*6)+(5*1)+(4*5)+(3*7)+(2*4)+(1*7)=141
141 % 10 = 1
So 1056157-47-1 is a valid CAS Registry Number.

Palladium-Catalyzed Hydroamidocarbonylation of Olefins to Imides

Li, Haoquan,Dong, Kaiwu,Neumann, Helfried,Beller, Matthias

, p. 10239 - 10243 (2015)

Carbonylation reactions allow the efficient synthesis of all kinds of carbonyl-containing compounds. Here, we report a straightforward synthesis of various imides from olefins and CO for the first time. The established hydroamidocarbonylation reaction affords imides in good yields (up to 90%) and with good regioselectivity (up to 99:1) when applying different alkenes and amides. The synthetic potential of the method is highlighted by the synthesis of Aniracetam by intramolecular hydroamidocarbonylation.
