Check Digit Verification of cas no

The CAS Registry Mumber 1242176-12-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,1,7 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1242176-12:
(9*1)+(8*2)+(7*4)+(6*2)+(5*1)+(4*7)+(3*6)+(2*1)+(1*2)=120
120 % 10 = 0
So 1242176-12-0 is a valid CAS Registry Number.

Cyclization of (1,2,4,5-tetrazin-3-yl)hydrazones to 3,7-dihydro-1,2,4- triazolo[4,3-b]-1,2,4,5-tetrazines

Tolshchina,Vyakhireva,Ignatenko,Ishmetova,Ganebnykh,Slepukhin,Rusinov

, p. 1281 - 1290 (2010/10/04)

The intramolecular cyclization of (6-R-1,2,4,5-tetrazin-3-yl)hydrazones of ketones (R is 3,5-dimethylpyrazol-1-yl, 4-methylimidazol-1-yl, or 2-alkylidenehydrazino) giving rise to the previously unknown ,7-dihydro-1,2,4-triazolo[4,3-b]-1,2,4,5-tetrazines, including spiro com-pounds, was studied. The reactivity and the yields of the reaction products depend on the structure of the alkylidene fragment and the nature of the substituent in the tetrazine ring. ; 2009 Springer Science+Business Media, Inc.
