18203-32-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18203-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18203-32:
(7*1)+(6*8)+(5*2)+(4*0)+(3*3)+(2*3)+(1*2)=82
82 % 10 = 2
So 18203-32-2 is a valid CAS Registry Number.

Intermolecular Trifluoromethyl-Hydrazination of Alkenes Enabled by Organic Photoredox Catalysis

Gong, Yuefa,Lu, Dengfu,Wang, Peng,Zhu, Songsong

, p. 1924 - 1928 (2020)

A metal-free and redox-neutral trifluoromethyl-hydrazination method of alkenes is described. With a commercially available photocatalyst and low-cost reagents, both conjugated and isolated alkenes could be converted to β-trifluoromethyl hydrazines in good

Nickel-catalyzed reductive 1,3-diene formation from the cross-coupling of vinyl bromides

Sha, Yunfei,Liu, Jiandong,Wang, Liang,Liang, Demin,Wu, Da,Gong, Hegui

supporting information, p. 4887 - 4890 (2021/06/16)

Facile construction of 1,3-dienes building upon cross-electrophile coupling of two open-chain vinyl halides is disclosed in this work, showing moderate chemoselectivities between the terminal bromoalkenes and internal vinyl bromides. The present method is mild and tolerates a range of functional groups and can be applied to the total synthesis of a tobacco fragrance solanone.
