The 3 and 5 positions of the pyridine ring are substituted with carboxylic acid groups, which are further esterified with ethyl groups, resulting in diethyl esters. 4-hydroxy-1-methyl-2,6-diphenyl-1,2,3,6-tetrahydro-pyridine-3,5-dicarboxylic acid diethyl ester is likely to be used in the synthesis of various pharmaceuticals or other organic compounds due to its unique structure and functional groups.
The CAS Registry Mumber 2653-02-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 3 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2653-02: (6*2)+(5*6)+(4*5)+(3*3)+(2*0)+(1*2)=73 73 % 10 = 3 So 2653-02-3 is a valid CAS Registry Number.
