Check Digit Verification of cas no

The CAS Registry Mumber 1087644-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,7,6,4 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1087644-25:
(9*1)+(8*0)+(7*8)+(6*7)+(5*6)+(4*4)+(3*4)+(2*2)+(1*5)=174
174 % 10 = 4
So 1087644-25-4 is a valid CAS Registry Number.

Copper-Catalyzed Tandem Reactions of 2-Amine-[1,3,5]triazines with Nitriles

Zhang, Li-Yu,Zhang, Chen,Wang, Tao,Shi, Yu-Long,Ban, Meng-Tao,Cui, Dong-Mei

, p. 536 - 543 (2019)

Copper-catalyzed intermolecular annulation of 2-amine-[1,3,5]triazines and aryl nitriles for the synthesis of [1,2,4]triazolo[1,5-a][1,3,5]triazines via N-C bond formation and oxidative N-N coupling [oxidative 3 + 2 cyclization] is presented. A wide range of aryl nitriles, including electron-rich benzonitriles, electron-poor benzonitriles, 2-cyanothiophene, and 4-cyanopyridine, were all functionalized with 2-amine-[1,3,5]triazines. Furthermore, amidation of 2-amine-[1,3,5]triazines via Cu-catalyzed C-CN bond cleavage of phenylacetonitriles is also demonstrated. The reaction occurred in moderate to satisfactory yields and tolerated alkyl- or aryl-substituted 2-amine-[1,3,5]triazines. Aniline, aminopyridine, and aminopyrimidine also afforded the desired products.
