108134-82-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108134-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,3 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108134-82:
(8*1)+(7*0)+(6*8)+(5*1)+(4*3)+(3*4)+(2*8)+(1*2)=103
103 % 10 = 3
So 108134-82-3 is a valid CAS Registry Number.

SYNTHESIS OF 4-SUBSTITUTED 3-PYRIDYL KETONES
Comins, Daniel L.,Stroud, Eric D.
, p. 3199 - 3201 (2007/10/02)
In the presence of a catalytic amount of cuprous iodide, the addition of Grignard reagents to the 1-phenoxycarbonyl salts of 3-acylpyridines gives 3-acyl-4-alkyl-1-phenoxycarbonyl-1,4-dihydropyridines.The crude dihydropyridines were aromatized with hot su
