1226791-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1226791-19-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,7,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1226791-19:
(9*1)+(8*2)+(7*2)+(6*6)+(5*7)+(4*9)+(3*1)+(2*1)+(1*9)=160
160 % 10 = 0
So 1226791-19-0 is a valid CAS Registry Number.

An efficient and convenient synthesis of ethyl 1-(4-Methoxyphenyl)-5- phenyl-1H-1,2,3-triazole-4-carboxylate
Chen, Jung-Hsuan,Liu, Shuan-Ru,Chen, Kwunmin
, p. 328 - 333 (2010)
The "click chemistry" of using organic azides and terminal alkynes is arguably the most efficient and straightforward route to the synthesis of 1,2,3-triazoles. In this paper, an alternative and direct access to ethyl 1-(4-methoxyphenyl)-5-phenyl-1H-1,2,3
