116905-38-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116905-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,0 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116905-38:
(8*1)+(7*1)+(6*6)+(5*9)+(4*0)+(3*5)+(2*3)+(1*8)=125
125 % 10 = 5
So 116905-38-5 is a valid CAS Registry Number.

Di- tert-butyl Peroxide-Mediated Radical C(sp2/sp3)-S Bond Cleavage and Group-Transfer Cyclization

Luo, Kai,Yang, Wen-Chao,Wei, Kai,Liu, Yue,Wang, Jun-Ke,Wu, Lei

supporting information, p. 7851 - 7856 (2019/10/11)

A novel strategy of cascade radical C(sp2/sp3)-S bond cleavage and group-transfer cyclization is disclosed. Triggered by alkyl radicals, varieties of 2-isocyanoaryl thioethers containing aliphatic, aryl, and heteroaromatic groups can be cleaved and precisely reinstalled to give benzothiazole derivatives. Mechanistic studies reveal that the cascade reaction undertakes an intermolecular pathway, and the inner radical sources (R radicals) exhibit high priority over those of methyl radical origin from di-tert-butyl peroxide.
