Check Digit Verification of cas no

The CAS Registry Mumber 107572-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,5,7 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107572-59:
(8*1)+(7*0)+(6*7)+(5*5)+(4*7)+(3*2)+(2*5)+(1*9)=128
128 % 10 = 8
So 107572-59-8 is a valid CAS Registry Number.

Facile synthesis of 3,5-diaryl-1,2,4-triazoles via copper-catalyzed domino nucleophilic substitution/oxidative cyclization using amidines or imidates as substrates

Sudheendran, Kavitha,Schmidt, Dietmar,Frey, Wolfgang,Conrad, Jürgen,Beifuss, Uwe

, p. 1635 - 1645 (2014/02/14)

Two methods for the synthesis of 3,5-diaryl-1,2,4-triazoles, both domino reactions, are reported. The first procedure, the Cu(OTf)2-catalyzed reaction between two amidines using NaHCO3 as a base, 1,10-phenanthroline as an additive and K3[Fe(CN)6]/ atmospheric oxygen as the oxidant, delivers 3,5-diaryl-1,2,4-triazoles with yields up to 68%. The second procedure for the synthesis of 3,5-diaryl-1,2,4- triazoles with yields up to 64% rests on the Cu(OTf)2-catalyzed reaction between two imidates and ammonium carbonate. This method features the formation of three bonds in a single synthetic step.
