Check Digit Verification of cas no

The CAS Registry Mumber 3840-33-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3840-33:
(6*3)+(5*8)+(4*4)+(3*0)+(2*3)+(1*3)=83
83 % 10 = 3
So 3840-33-3 is a valid CAS Registry Number.

Palladium-Catalyzed meta-C-H Olefination of Arene-Tethered Diols Directed by Well-Designed Pyrimidine-Based Group

Fang, Siqiang,Wang, Xiaobing,Yin, Fucheng,Cai, Pei,Yang, Huali,Kong, Lingyi

supporting information, (2019/03/19)

The palladium-catalyzed meta-olefination of arene-tethered diols attached to a well-designed pyrimidine moiety is presented. Applications of the protocol are illustrated by the synthesis of various diol-based natural products, such as coumarins, phenylpropanoids, stilbenes, and chalcones. Advantages of this method are demonstrated through the easy removal of the template and a gram-scale olefination reaction. Finally, experimental verification, including 1H NMR, ESI-MS and IR, and DFT studies are undertaken to elucidate the mechanistic complexity.

Palladium-catalyzed oxidative allylation of bis[(pinacolato)boryl]methane: Synthesis of homoallylic boronic esters

Li, Chunsheng,Li, Meng,Li, Jianxiao,Wu, Wanqing,Jiang, Huanfeng

supporting information, p. 66 - 69 (2017/12/27)

A palladium-catalyzed oxidative allylation of bis[(pinacolato)boryl]methane to afford the corresponding homoallylic organoboronic esters with moderate to excellent yields is reported. This novel transformation provides an efficient strategy for the construction of homoallylic organoboronic esters in one step with a broad substrate scope. It is proposed that the palladium-catalyzed oxidative allylic C-H bond activation process may be involved in the catalytic cycle.
