Check Digit Verification of cas no

The CAS Registry Mumber 40125-46-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,2 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40125-46:
(7*4)+(6*0)+(5*1)+(4*2)+(3*5)+(2*4)+(1*6)=70
70 % 10 = 0
So 40125-46-0 is a valid CAS Registry Number.

Novel 3-benzylidene/benzylphthalide Mannich base derivatives as potential multifunctional agents for the treatment of Alzheimer's disease

Cao, Zhongcheng,Song, Qing,Yu, Guangjun,Liu, Zhuoling,Cong, Shiqing,Tan, Zhenghuai,Deng, Yong

, (2021/03/01)

To discover novel multifunctional agents for the treatment of Alzheimer's disease, a series of 3-benzylidene/benzylphthalide Mannich base derivatives were designed, synthesized and evaluated. The biological screening results indicated that most of these d

A one-pot synthesis of new 3-benzylphthalide derivatives was developed by using a strategy based on tetrakis(dimethylamino)ethylene (TDAE). The reactions in the presence of TDAE of substituted benzyl chlorides with methyl 2-formylbenzoate or of substitute

Indandione-Terminated Quinoids: Facile Synthesis by Alkoxide-Mediated Rearrangement Reaction and Semiconducting Properties

Du, Tian,Gao, Ruiheng,Deng, Yunfeng,Wang, Cheng,Zhou, Qian,Geng, Yanhou

supporting information, p. 221 - 225 (2019/11/28)

A series of 1,3-indandione-terminated π-conjugated quinoids were synthesized by alkoxide-mediated rearrangement reaction of the respective alkene precursors, followed by air oxidation. This new protocol allows access to quinoidal compounds with variable termini and cores. The resulting quinoids all show LUMO levels below ?4.0 eV and molar extinction coefficients above 105 L mol?1 cm?1. The optoelectronic properties of these compounds can be regulated by tuning the central cores as well as the aryl termini ascribed to the delocalized frontier molecular orbitals over the entire molecular skeleton involving aryl termini. n-Channel organic thin-film transistors with electron mobility of up to 0.38 cm2 V?1 s?1 were fabricated, showing the potential of this new class of quinoids as organic semiconductors.
