Check Digit Verification of cas no

The CAS Registry Mumber 55919-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55919-44:
(7*5)+(6*5)+(5*9)+(4*1)+(3*9)+(2*4)+(1*4)=153
153 % 10 = 3
So 55919-44-3 is a valid CAS Registry Number.

Acylation of aryl halides and α-bromo acetates with aldehydes enabled by nickel/tbadt cocatalysis

Fan, Pei,Zhang, Chang,Zhang, Linchuan,Wang, Chuan

supporting information, p. 3875 - 3878 (2020/05/14)

In this protocol aryl halides and α-bromo acetates are efficiently cross-coupled with an array of (hetero)aromatic and aliphatic aldehydes under the cooperative catalysis of nickel and tetrabutylammonium decatungstate as a hydrogen-atom-transfer photocatalyst. This method provides a concise approach to a variety of ketones with high compatibility of various functional groups.

Synthesis of 1H-isoindol-3-amine derivatives by iodine-mediated cyclization of 2-vinylbenzamidine derivatives

Kobayashi, Kazuhiro,Horiuchi, Mai,Fukamachi, Shuhei,Konishi, Hisatoshi

experimental part, p. 669 - 677 (2009/06/08)

It has been found that the reaction of 2-vinylbenzamidine derivatives, prepared by reacting 2-vinylbenzonitriles with lithium cyclic secondary amides, with iodine in the presence of sodium hydrogen carbonate in acetonitrile resulted in the formation of th
