Check Digit Verification of cas no

The CAS Registry Mumber 21864-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,6 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21864-84:
(7*2)+(6*1)+(5*8)+(4*6)+(3*4)+(2*8)+(1*4)=116
116 % 10 = 6
So 21864-84-6 is a valid CAS Registry Number.

Palladium-Catalyzed Synthesis of α-Iminonitriles from Aryl Halides via Isocyanide Double Insertion Reaction

Chen, Zhen-Bang,Zhang, Ying,Yuan, Qing,Zhang, Fang-Ling,Zhu, Yong-Ming,Shen, Jing-Kang

, p. 1610 - 1616 (2016/03/01)

An efficient one-pot synthesis of α-iminonitriles from readily available aryl halides via palladium-catalyzed double isocyanide insertion and elimination has been developed, without using various hypertoxic cyanides and excess oxidants. Furthermore, the utility of this reaction was demonstrated by the rapid total synthesis of quinoxaline and the reaction of functional groups exchanged with aryl halides. (Chemical Equation Presented).
