161525-14-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 161525-14-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,5,2 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161525-14:
(8*1)+(7*6)+(6*1)+(5*5)+(4*2)+(3*5)+(2*1)+(1*4)=110
110 % 10 = 0
So 161525-14-0 is a valid CAS Registry Number.

An improved preparation of 3-alkoxypyrazoles

Guillou, Sandrine,Bonhomme, Frederic J.,Janin, Yves L.

experimental part, p. 3504 - 3508 (2009/05/09)

The condensation between alkyl acetoacetates and hydrazines constitutes the very well-known Knorr synthetic method leading to pyrazol-3/5-ones. However, contemporary reports describe an alternate reaction pathway leading to low yields of 3/5-alkoxypyrazoles using hydrazine salts. No general method for the selective synthesis of 3-alkoxypyrazoles has been reported to date, hence we focused on this side reaction in an attempt to turn it into the main transformation. Depending on the starting material, various 3-alkoxypyrazoles (methoxy, ethoxy, benzyloxy, isopropoxy, allyloxy) were obtained in up to 56% yield. Georg Thieme Verlag Stuttgart.
