874117-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874117-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,1 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 874117-16:
(8*8)+(7*7)+(6*4)+(5*1)+(4*1)+(3*7)+(2*1)+(1*6)=175
175 % 10 = 5
So 874117-16-5 is a valid CAS Registry Number.

Synthesis of β-(N-1,2,3-triazolyl)- substituted α,β-unsaturated α- amino acid derivatives. A new example of 1H- to 2H-1,2,3-triazole isomerisation
Polak, Matjaz,Vercek, Bojan
, p. 2863 - 2871 (2000)
Synthesis of β-1H-1,2,3-triazol-1-yl and β-2H-1,2,3-triazol-2-yl α,β-unsaturated α-amino acid derivatives is reported. 1H-1,2,3-Triazole 4 was found to isomerise to the corresponding 2H-1,2,3-triazole 7.
