84859-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84859-30-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84859-30:
(7*8)+(6*4)+(5*8)+(4*5)+(3*9)+(2*3)+(1*0)=173
173 % 10 = 3
So 84859-30-3 is a valid CAS Registry Number.

Condensation of o-Diamines with Dehydroacetic Acid and Pyrolysis of Resultant Products
Qayyoom, M. A.,Hanumanthu, P.,Ratnam, C. V
, p. 883 - 884 (2007/10/02)
Condensation of o-phenylenediamines with dehydroacetic acid (I) yields 3--4-hydroxy-6-methyl-2(H)-pyrones (II), which on pyrolysis give the corresponding 2-methylbenzimidazoles (V).
