Check Digit Verification of cas no

The CAS Registry Mumber 128979-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,7 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128979-27:
(8*1)+(7*2)+(6*8)+(5*9)+(4*7)+(3*9)+(2*2)+(1*7)=181
181 % 10 = 1
So 128979-27-1 is a valid CAS Registry Number.

Hetero-Diels-Alder reactions of novel 3-triazolyl-nitrosoalkenes as an approach to functionalized 1,2,3-triazoles with antibacterial profile

Lopes, Susana M.M.,Novais, Juliana S.,Costa, Dora C.S.,Castro, Helena C.,Figueiredo, Agnes Marie S.,Ferreira, Vitor F.,Pinho e Melo, Teresa M.V.D.,da Silva, Fernando de Carvalho

, p. 1010 - 1020 (2017/12/15)

The generation and reactivity of 3-triazolyl-nitrosoalkenes are reported for the first time. The study showed that hetero-Diels-Alder reaction of these heterodienes is an interesting synthetic strategy to functionalized 1,2,3-triazoles, including 1,2,3-tr

Copper(I)-catalyzed aerobic oxidative azide-alkene cyclo-addition: An efficient synthesis of substituted 1,2,3-triazoles

Janreddy, Donala,Kavala, Veerababurao,Kuo, Chun-Wei,Chen, Wen-Chang,Ramesh, Chintakunta,Kotipalli, Trimurtulu,Kuo, Ting-Shen,Chen, Mei-Ling,He, Chiu-Hui,Yao, Ching-Fa

, p. 2918 - 2927 (2014/03/21)

A novel, copper(I)-promoted azide-alkene aerobic oxidative cycloaddition protocol was devel-oped for the regioselective synthesis of 1,4-disubsti-tuted/ 1,4,5-trisubstituted 1,2,3-triazoles by using azides and electron-deficient olefins under an oxygen atmosphere.
