The CAS Registry Mumber 721945-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,9,4 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 721945-24:
(8*7)+(7*2)+(6*1)+(5*9)+(4*4)+(3*5)+(2*2)+(1*4)=160
160 % 10 = 0
So 721945-24-0 is a valid CAS Registry Number.

Pd-Catalyzed Three-Component Reaction of Anilines, Ethyl Vinyl Ether, and Nitro-Paraffin: Assembly of β-Nitroamines

Ouyang, Lu,Zhan, Lingzhi,Li, Jianxiao,Zhang, Qiaoyu,Qi, Chaorong,Wu, Wanqing,Jiang, Huanfeng

, p. 550 - 553 (2018)

A novel palladium-catalyzed amination and nitration of ethyl vinyl ether for the construction of β-nitroamine derivatives under mild conditions has been developed. This transformation provides a new strategy for the installation of amino and nitro from aromatic amines and nitro-paraffin into alkenes. Morpholine resulted in the aza-Henry reaction, while DABCO led to the unexpected rearrangement.
