1192413-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1192413-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,4,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1192413-22:
(9*1)+(8*1)+(7*9)+(6*2)+(5*4)+(4*1)+(3*3)+(2*2)+(1*2)=131
131 % 10 = 1
So 1192413-22-1 is a valid CAS Registry Number.

Synthesis and hydroxylation of 1-alkyl- and 7-alkyl- 1,3,7-triazapyrenium salts
Pisarenko,Demidov,Aksenov,Borovlev
experimental part, p. 580 - 586 (2010/02/28)
The regioselectivity of quaternization of 1,3,5-triazapyrenes by alkyl halides has been studied. Oxidative hydroxylation of 1-alkyl- and 7-alkyl-1,3,7-triazapyrenium salts gives 1-alkyl-1,2-dihydro-1,3,7-triazapyren- 2-ones or 7-alkyl-6,7-dihydro-1,3,7-tr
