Check Digit Verification of cas no

The CAS Registry Mumber 4513-27-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4513-27:
(6*4)+(5*5)+(4*1)+(3*3)+(2*2)+(1*7)=73
73 % 10 = 3
So 4513-27-3 is a valid CAS Registry Number.

Synthesis of 2-Imidazolines via Palladium-Catalyzed Cyclization Reaction of 2,3-Allenyl Amines and Aryl Iodides

Fang, Zixuan,Hu, Jinxing,Liang, Xiaoxia,Liu, Yanjun,Liu, Yue,Lu, Rongmei,Wang, Shaoyu,Zeng, Xianzhong,Zhang, Cheng

, p. 901 - 908 (2020/03/13)

An effective method for the synthesis of polysubstituted 2-imidazoline derivatives via palladium-catalyzed cyclization of 2,3-allenyl amines with aryl iodides is described. This pure domino process allows the formation of new carbon-carbon and carbon-nitrogen bonds in a single synthetic operation.
