Check Digit Verification of cas no

The CAS Registry Mumber 125655-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,5 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125655-98:
(8*1)+(7*2)+(6*5)+(5*6)+(4*5)+(3*5)+(2*9)+(1*8)=143
143 % 10 = 3
So 125655-98-3 is a valid CAS Registry Number.

Synthesis and absorption abilities of pyrazolo[5,1-c][1,2,4]triazine-based disperse dyes

Karc?,Karci

, p. 457 - 465 (2013/07/26)

A series of 13 novel pyrazolo[5,1-c][1,2,4]triazine-based disperse dyes was synthesized by heating ethyl pyrazolylhydrazonocyanoacetate in glacial acetic acid. Solvent and acid-base influences on the wavelength of maximum absorption have been studied.

STUDIES ON CONDENSED PYRAZOLES: SYNTHESIS OF NEW METHYL AND AMINO PYRAZOLOPYRIMIDINES AND OF PYRAZOLOTRIAZINES

Hilmy Elnagdi, Mohamed,Hassen Taha, Nadia,Abdel Maksoud Abd El All, Fatma,Maawad Abdel-Motaleb, Ramadan,Farouk Mahmoud, Fivian

, p. 1082 - 1091 (2007/10/02)

A variety of 3-arylazo 5-amino- and 7-aminopyrazolo-pyrimidines were obtained via reacting Ia-Id with cinnamonitriles.The structure of products was confirmed via 1H NMR.Both 5-amino- and 7-amino-3-arylazo pyrazolopyrimidines reacted, with protons in acetic acid-sulphuric acid mixture to yield the corresponding 3-unsubstituted acetylaminopyrazolopyrimidines.Diazotized Ia and Ib coupled with a variety of active methylene reagents to yield pyrazolotriazines.
