Check Digit Verification of cas no

The CAS Registry Mumber 1013905-88-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,3,9,0 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1013905-88:
(9*1)+(8*0)+(7*1)+(6*3)+(5*9)+(4*0)+(3*5)+(2*8)+(1*8)=118
118 % 10 = 8
So 1013905-88-8 is a valid CAS Registry Number.

Visible-light-mediated selective thiocyanation/ipso-cyclization/oxidation cascade for the synthesis of thiocyanato-containing azaspirotrienediones

Chen, Yuan,Chen, Yu-Jue,Guan, Zhi,He, Yan-Hong

, (2019)

A visible-light-mediated metal-free thiocyanate radical addition/ipso-cyclization/oxidation cascade reaction for the synthesis of thiocyanato-containing azaspirotrienediones from N-phenylpropynamides is described. Cheap and readily available ammonium thiocyanate was used as a precursor to the thiocyanate free radical, which undergoes a radical addition reaction with the alkyne, followed by selective ipso-cyclization and oxidation to afford the dearomatized products. No product of ortho-cyclization was detected. The reaction completes the synthesis of C–S, C–C, and C[dbnd]O bonds in one pot, with abundant and renewable air oxygen as the sole sacrificial reagent and oxygen source.

Copper-catalyzed difunctionalization of activated alkynes by radical oxidation-tandem cyclization/dearomatization to synthesize 3-trifluoromethyl spiro[4.5]trienones

Hua, Hui-Liang,He, Yu-Tao,Qiu, Yi-Feng,Li, Ying-Xiu,Song, Bo,Gao, Pin,Song, Xian-Rong,Guo, Dong-Hui,Liu, Xue-Yuan,Liang, Yong-Min

supporting information, p. 1468 - 1473 (2015/01/30)

A copper-catalyzed difunctionalizing trifluoromethylation of activated alkynes with the cheap reagent sodium trifluoromethanesulfinate (NaSO2CF3 or Langlois' reagent) has been developed incorporating a tandem cyclization/ dearomatiza

Efficient palladium-catalyzed Suzuki-Miyaura cross-coupling of iodoethynes with arylboronic acids under aerobic conditions

Tang, Jian-Sheng,Xie, Ye-Xiang,Wang, Zhi-Qiang,Li, Jin-Heng

experimental part, p. 2789 - 2795 (2011/10/18)

Ligand-free palladium-catalyzed Suzuki-Miyaura cross-coupling of iodoethynes with arylboronic acids under aerobic conditions has been developed. In the presence of palladium(II) acetate and cesium carbonate, a variety of iodoethynes underwent the Suzuki-M
