Check Digit Verification of cas no

The CAS Registry Mumber 1242029-29-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,2 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1242029-29:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*2)+(3*9)+(2*2)+(1*9)=113
113 % 10 = 3
So 1242029-29-3 is a valid CAS Registry Number.

Copper-catalyzed three-component cyanotrifluoromethylation/ azidotrifluoromethylation and carbocyclization of 1,6-enynes

He, Yu-Tao,Li, Lian-Hua,Zhou, Zhao-Zhao,Hua, Hui-Liang,Qiu, Yi-Feng,Liu, Xue-Yuan,Liang, Yong-Min

, p. 3896 - 3899 (2014)

A novel three-component strategy for the cyanotrifluoromethylation/ azidotrifluoromethylation and carbocyclization of 1,6-enynes is developed. The reaction proceeds smoothly under a moderate temperature by using a copper catalyst, which provides a rapid a

Palladium-Catalyzed Radical Cascade Iododifluoromethylation/Cyclization of 1,6-Enynes with Ethyl Difluoroiodoacetate

Wang, Yu-Qi,He, Yu-Tao,Zhang, Lu-Lu,Wu, Xin-Xing,Liu, Xue-Yuan,Liang, Yong-Min

supporting information, p. 4280 - 4283 (2015/09/15)

A novel and convenient Pd-catalyzed radical cascade iododifluoromethylation/cyclization of 1,6-enynes with ethyl difluoroiodoacetate is demonstrated. The proposed transformation presents high stereoselectivity under mild and facile reaction conditions, th

Copper-catalyzed trifluoromethylation-cyclization of enynes: Highly regioselective construction of trifluoromethylated carbocycles and heterocycles

Gao, Pin,Yan, Xiao-Biao,Tao, Tao,Yang, Fan,He, Ting,Song, Xian-Rong,Liu, Xue-Yuan,Liang, Yong-Min

supporting information, p. 14420 - 14424 (2013/11/06)

Regioselective trifluoromethylation-cyclization: A method for copper-catalyzed trifluoromethylation-cyclization of simple enynes using the C-C triple bond as a nucleophile is reported for the first time (see scheme). The reaction proceeds efficiently in a
