1210483-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1210483-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,4,8 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1210483-52:
(9*1)+(8*2)+(7*1)+(6*0)+(5*4)+(4*8)+(3*3)+(2*5)+(1*2)=105
105 % 10 = 5
So 1210483-52-5 is a valid CAS Registry Number.

Synthesis of pyridin-2(1H)-ones by the intramolecular cyclization of amides of β-enamino ketones
Goncharov,Kostuchenko,Fisyuk
experimental part, p. 793 - 795 (2010/04/02)
It has been shown that intramolecular cyclization of N-(1-methyl-3-oxobut- 1-en-1-yl)phenyl- and -tosylacetamides in basic media lead to 3-phenyl- and 3-tosyl-substituted 4,6-dimethylpyridin-2(1H)-ones.
