Check Digit Verification of cas no

The CAS Registry Mumber 18951-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,5 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18951-44:
(7*1)+(6*8)+(5*9)+(4*5)+(3*1)+(2*4)+(1*4)=135
135 % 10 = 5
So 18951-44-5 is a valid CAS Registry Number.

Iron-Catalyzed Nitrene Transfer Reaction of 4-Hydroxystilbenes with Aryl Azides: Synthesis of Imines via C=C Bond Cleavage

Peng, Yi,Fan, Yan-Hui,Li, Si-Yuan,Li, Bin,Xue, Jing,Deng, Qing-Hai

supporting information, p. 8389 - 8394 (2019/10/16)

C=C bond breaking to access the C=N bond remains an underdeveloped area. A new protocol for C=C bond cleavage of alkenes under nonoxidative conditions to produce imines via an iron-catalyzed nitrene transfer reaction of 4-hydroxystilbenes with aryl azides is reported. The success of various sequential one-pot reactions reveals that the good compatibility of this method makes it very attractive for synthetic applications. On the basis of experimental observations, a plausible reaction mechanism is also proposed.

Decarboxylation of α,β-unsaturated aromatic lactones: Synthesis of: E-ortho -hydroxystilbenes from 3-arylcoumarins or isoaurones

Huang, Xihua,Liu, Jie,Sheng, Jianfei,Song, Xianheng,Du, Zhibo,Li, Mingkang,Zhang, Xuejing,Zou, Yong

supporting information, p. 804 - 808 (2018/03/06)

A simple and environmentally friendly strategy for the synthesis of E-ortho-hydroxystilbenes has been established. Two kinds of α,β-unsaturated aromatic lactones, i.e. the 3-arylcoumarins and the isoaurones, could both readily undergo a cascade hydrolyzation/decarboxylation reaction in the presence of KOH in ethylene glycol to afford the desired E-ortho-hydroxystilbenes in moderate to high yields.
