50847-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50847-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,8,4 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50847-07:
(7*5)+(6*0)+(5*8)+(4*4)+(3*7)+(2*0)+(1*7)=119
119 % 10 = 9
So 50847-07-9 is a valid CAS Registry Number.

Reactivity of diazoazoles and azolediazonium salts in C-azo coupling reactions
Sadchikova,Mokrushin
, p. 354 - 365 (2005)
The comparative reactivity of heterocyclic diazo compounds and the corresponding diazonium salts in C-azo coupling reactions was studied using imidazole, pyrazole, and triazole derivatives as examples.The reactivities of pyrazole- and imidazole-derived di
