Check Digit Verification of cas no

The CAS Registry Mumber 77063-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,6 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77063-21:
(7*7)+(6*7)+(5*0)+(4*6)+(3*3)+(2*2)+(1*1)=129
129 % 10 = 9
So 77063-21-9 is a valid CAS Registry Number.

Efficient Multigram Approach to Acetylenes and CF3-ynones Starting from Dichloroalkenes Prepared by Catalytic Olefination Reaction (COR)

Muzalevskiy, Vasiliy M.,Sizova, Zoia A.,Diusenov, Arstan I.,Shastin, Alexey V.,Nenajdenko, Valentine G.

, p. 4161 - 4166 (2020/07/13)

A novel approach to terminal acetylenes based on catalytic olefination reaction COR of arylaldehydes to form dichloroalkenes followed by treatment with nBuLi was elaborated. This method is atom economical and displays high yields and effectivity. The corresponding alkynes can be prepared in up to 97 % yield. One pot procedure towards CF3-ynones was elaborated to provide these products in up to 87 % yield starting from dichloroalkenes.

Study on the green click-chemistry synthesis of 4-trifluoroacetyl-1,2,3-triazoles

Han, Jie,Ran, Jian-Xiong,Chen, Xiu-Ping,Wang, Zhong-Hua,Wu, Fan-Hong

, p. 6985 - 6992 (2018/10/31)

A metal-free and solvent free click-chemistry procedure has been revealed for the synthesis of 4-trifluoroacetyl-1,2,3-triazoles from corresponding azides and alkyne with high yield and selectivity. The pure products could be easily obtained via crystalli

Bronsted acid catalyzed friedel-crafts alkylation reactions of trifluoromethyl-α,β-ynones with indoles

Sasaki, Shigeru,Ikekame, Yuta,Tanayama, Manabu,Yamauchi, Takayasu,Higashiyama, Kimio

supporting information, p. 2699 - 2703,5 (2012/12/12)

The successful development of a Bronsted acid catalyzed Friedel-Crafts alkylation reaction between trifluoromethyl-α,β-ynones and indoles has been described. The reaction is catalyzed by benzoic acid (5 mol%), with the indoles adding to the carbonyl carbon of the trifluoromethyl-α,β- ynones producing the corresponding 1,2-addition products as trifluoromethyl propargyl alcohols in high yields. Furthermore, treatment of the product with indoles in the presence of trifluoroacetic acid (10 mol%) afforded trifluoromethyl-functionalized unsymmetrical bis(indolyl)propynes in high yields.
