Check Digit Verification of cas no

The CAS Registry Mumber 21719-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,1 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21719-77:
(7*2)+(6*1)+(5*7)+(4*1)+(3*9)+(2*7)+(1*7)=107
107 % 10 = 7
So 21719-77-7 is a valid CAS Registry Number.

Transition-metal-free three-component reaction: Additive controlled synthesis of sulfonylated imidazoles

Liu, Wei,Zhang, Yu,He, Jiaming,Yu, Yue,Yuan, Jiajun,Ye, Xiaoyi,Zhang, Ziwu,Xue, Liang,Cao, Hua

, p. 11348 - 11358 (2019)

Two efficient transition-metal-free highly regioselective pathways for constructing sulfonylated imidazoles via three-component reactions of amidines, ynals, and sodium sulfonates have been developed. The generations of different sulfonylated imidazoles w

Synthesis of 1,2-dihydro-1,3,5-triazine derivativesviaCu(ii)-catalyzed C(sp3)-H activation ofN,N-dimethylethanolamine with amidines

Chen, Rener,Ma, Renchao,Ma, Yongmin,Wang, Lei,Wang, Zhiming,Yan, Min

supporting information, p. 10946 - 10949 (2020/10/02)

1,2-Dihydro-1,3,5-triazines and symmetrical 1,3,5-triazines were obtained in up to 81% yields from amidines andN,N-dimethylethanolamine catalyzed by CuCl2. The reaction involves three C-N bond formations during the oxidative annulation process

Direct Access to 1,3,5-Trisubstituted 1 H -1,2,4-Triazoles from N -Phenylbenzamidines via Copper-Catalyzed Diamination of Aryl Nitriles

Zhang, Lutao,Tang, Dong,Gao, Jing,Wang, Jing,Wu, Ping,Meng, Xu,Chen, Baohua

, p. 3924 - 3930 (2016/11/11)

A copper-catalyzed formation of C-N/N-N bonds using N-phenylbenzamidines with aryl nitriles has been developed and affords a route to 1,3,5-trisubstituted 1H-1,2,4-triazoles in moderate to excellent yields. The method is operationally simple and environme
