Check Digit Verification of cas no
The CAS Registry Mumber 84490-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,9 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84490-12:
(7*8)+(6*4)+(5*4)+(4*9)+(3*0)+(2*1)+(1*2)=140
140 % 10 = 0
So 84490-12-0 is a valid CAS Registry Number.

Preparation of 1,3-dihydro-4-pyridoyl-2H-imidazol-2-ones
-
, (2008/06/13)
1,3-Dihydro-4-pyridoyl-2H-imidazol-2-ones are prepared in a three step process by (a) reducing 1-pyridyl-1,3-deketo-2-oximinoalkanes to produce 1-pyridyl-1-hydroxy-2-amine-3-ketoalkanes; (b) reacting the thus produced hydroxyaminoketone with cyanate ion to produce a 1,3-dihydro-4-hydroxy(pyridyl)methyl-2H-imidazol-2-one; and (c) oxidizing the thus produced hydroxymethyl compound to yield the desired product.
