Check Digit Verification of cas no

The CAS Registry Mumber 1180670-65-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,0,6,7 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1180670-65:
(9*1)+(8*1)+(7*8)+(6*0)+(5*6)+(4*7)+(3*0)+(2*6)+(1*5)=148
148 % 10 = 8
So 1180670-65-8 is a valid CAS Registry Number.

Synthesis of β-CF 3 Ketones through Copper/Silver Cocatalyzed Oxidative Coupling of Enol Acetates with ICH 2 CF 3

Xiong, Yi,Chen, De,Zeng, Sheng,Cheng, Chaozhihui,Wang, Pengjie,Deng, Wei,Xiang, Jiannan,Yi, Niannian

, p. 2279 - 2282 (2018)

A simple method for the synthesis of β-CF 3 ketones through copper/silver cocatalyzed oxidative coupling of enol acetates with ICH 2 CF 3 has been developed. Enol acetates were chosen as the source of carbonyl group, giving the β-CF 3 ketones in moderate yields. Control experiments imply that a radical process maybe involved in this reaction.

Base-Promoted Double-Bond-Migration/Hydrolysis/Isomerization of 4-Aryl-1,1,1-trifluorobut-2-en-2-yl Trifluoromethanesulfonates: A Metal-Free Approach to β-Trifluoromethyl Ketones

Zhou, Yuhan,Zhang, Chunxia,Zhao, Yilong,Li, Dong,Zhao, Jinfeng,Wang, Zhaotian,Qu, Jingping

, p. 6217 - 6222 (2018/11/23)

A method for the synthesis of β-trifluoromethyl ketones promoted by a base is described. In the presence of DBU, 1-aryl-4,4,4-trifluoromethylbutanones with various functional groups were obtained through the reaction of 4-aryl-1,1,1-trifluorobut-2-en-2-yl

Copper/Silver Cocatalyzed Oxidative Coupling of Vinylarenes with ICH2CF3 or ICH2CHF2 Leading to β-CF3/CHF2-Substituted Ketones

Yi, Niannian,Zhang, Hao,Xu, Chonghui,Deng, Wei,Wang, Ruijia,Peng, Dongming,Zeng, Zebing,Xiang, Jiannan

supporting information, p. 1780 - 1783 (2016/05/19)

A novel copper/silver cocatalyzed oxidative coupling of vinylarenes with ICH2CF3 or ICH2CHF2 through a radical process has been developed. The transformation provides an attractive approach to β-CF3/CHF2-substituted ketones, with the advantages of easily available starting materials and operational simplicity.
