Check Digit Verification of cas no

The CAS Registry Mumber 1236874-98-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,8,7 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1236874-98:
(9*1)+(8*2)+(7*3)+(6*6)+(5*8)+(4*7)+(3*4)+(2*9)+(1*8)=188
188 % 10 = 8
So 1236874-98-8 is a valid CAS Registry Number.

Copper-catalyzed three component C[sbnd]S/C[sbnd]N coupling for the synthesis of trifluorothioacetamides

Hu, Bo-Lun,Song, Yi-Kang,Yao, Zengwen,Zhang, Guoqiang,Zhang, Xing-Guo

, (2020/10/06)

A copper-catalyzed three component C[sbnd]S/C[sbnd]N coupling reaction of imines with sulfur and CFC-113a was developed. The reaction involves amination and C[dbnd]S double bond formation of CFC-113a, leading to biologically important trifluorothioacetamides. The method features efficient construction of trifluorothioacetyl moiety from cheap sulfur and CFC-113a, and safe disposal for environmentally persistent Freon

Switching reaction pathways of trifluoromethylated thiobenzanilides by choice of different oxidative systems

Zhu, Jiangtao,Xie, Haibo,Li, Shan,Chen, Zixian,Wu, Yongming

body text, p. 306 - 309 (2011/06/20)

Trifluoromethylated thiobenzanilides are efficiently converted to 2-trifluoromethylbenzothiazoles via intramolecular oxidative cyclization under CAN/NaHCO3 oxidation, while the dimerized products with "-S-S-" bond linkage are obtained when PIDA
