74880-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74880-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,8 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74880-42:
(7*7)+(6*4)+(5*8)+(4*8)+(3*0)+(2*4)+(1*2)=155
155 % 10 = 5
So 74880-42-5 is a valid CAS Registry Number.

Trichloroisocyanuric acid-promoted thiolation of phosphites by thiols

Chen, Yingying,Li, Meichao,Gong, Zhangshui,Shen, Zhenlu

, p. 19 - 27 (2020/08/06)

A simple and convenient method for the synthesis of thiophosphates by coupling of phosphites with thiols under mild conditions has been developed. The reactions were promoted by trichloroisocyanuric acid (TCCA) and were carried out at room temperature in

Formation of α-chalcogenyl acrylamides through unprecedented chalcogen-mediated metal-free oxyfunctionalization of ynamides with DMSO as an oxidant

Huang, Hai,Tang, Luning,Liu, Qi,Xi, Yang,He, Guangke,Zhu, Hongjun

supporting information, p. 5605 - 5608 (2016/05/09)

A novel chalcogen-mediated oxyfunctionalization mode of ynamides for the synthesis of α-chalcogenyl acrylamides has been developed. Independent of metal catalysts, external oxidants and additives, this mild process afforded a range of structurally diverse
