40805-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40805-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,0 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40805-62:
(7*4)+(6*0)+(5*8)+(4*0)+(3*5)+(2*6)+(1*2)=97
97 % 10 = 7
So 40805-62-7 is a valid CAS Registry Number.

A practical synthesis of α-bromo/iodo/chloroketones from olefins under visible-light irradiation conditions

Wang, Zhihui,Wang, Lei,Wang, Zhiming,Li, Pinhua,Zhang, Yicheng

supporting information, p. 429 - 432 (2020/02/29)

A practical synthesis of α-bromo/iodo/chloroketones from olefins under visible-light irradiation conditions has been developed. In the presence of PhI(OAc)2 as promoter and under ambient conditions, the reactions of styrenes and triiodomethane undergo the transformation smoothly to deliver the corresponding α-iodoketones without additional photocatalyst in good yields under sunlight irradiation. Meanwhile, the reactions of styrenes with tribromomethane and trichloromethane generate the desired α-bromoketones and α-chloroketones in high yields by using Ru(bpy)3Cl2 as a photocatalyst under blue LED (450–455 nm) irradiation.

Natural products as sources of new fungicides (V): Design and synthesis of acetophenone derivatives against phytopathogenic fungi in vitro and in vivo

Dan, Wen-Jia,Tuong, Thi-Mai-Luong,Wang, Da-Cheng,Li, Ding,Zhang, An-Ling,Gao, Jin-Ming

, p. 2861 - 2864 (2018/07/25)

A series of acetophenone derivatives (10a–10i, 11, 12a–12g, 13a–13g, 14a–14d and 15a–15l) were designed, synthesized and evaluated for antifungal activities in vitro and in vivo. The antifungal activities of 53 compounds were tested against several plant pathogens, and their structure–activity relationship was summarized. Compounds 10a–10f displayed better antifungal effects than two reference fungicides. Interestingly, the most potent compound 10d exhibited antifungal properties against Cytospora sp., Botrytis cinerea, Magnaporthe grisea, with IC50 values of 6.0–22.6 μg/mL, especially Cytospora sp. (IC50 = 6.0 μg/mL). In the in vivo antifungal assays, 10d displayed the significant protective efficacy of 55.3% to Botrytis cinerea and 73.1% to Cytospora sp. The findings indicated that 10d may act as a potential pesticide lead compound that merits further investigation.
