159718-76-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159718-76-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159718-76:
(8*1)+(7*5)+(6*9)+(5*7)+(4*1)+(3*8)+(2*7)+(1*6)=180
180 % 10 = 0
So 159718-76-0 is a valid CAS Registry Number.

Synthesis of New ν-Triazolopyrimidinium Salts
Batori, S.,Messmer, A.
, p. 1041 - 1046 (2007/10/02)
New ν-triazolo- and ν-triazolopyrimidinium salts 12a-e, 13a-c have been synthesized via oxidation (i.e. cyclohydrogenation) of the appropriate pyrimidyl ketone arylhydrazones 3a-e, 6a-c using TBB (2,4,4,6-tetrabromocyclohexa-2,5-dien-1-one)
