Check Digit Verification of cas no

The CAS Registry Mumber 1034767-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,4,7,6 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1034767-34:
(9*1)+(8*0)+(7*3)+(6*4)+(5*7)+(4*6)+(3*7)+(2*3)+(1*4)=144
144 % 10 = 4
So 1034767-34-4 is a valid CAS Registry Number.

Synthesis and study of reactivity of pyrrolo[3,2-e][1,2,4]-triazine system1

Styskala, Jakub,Slouka, Jan,Cankar, Petr

, p. 1087 - 1095 (2008/12/20)

The corresponding 2-arylhydrazones 5 were obtained by coupling of diazonium salts with diethyl (3-methyl-1H-pyrrole)-2,4-dicarbamate 4. These ones were cyclized in a alkaline medium to ethyl (2-aryl-5-methyl-3-oxo-2,3-dihydro-7H-pyrrolo[3,2-e][1,2,4]triazin-6-yl)carbamates 6 and tested for their stability. The starting carbamate 4 was prepared by a multistep synthesis from diethyl 3-methyl-1H-pyrrole-2,4-dicarboxylate 1.
