Check Digit Verification of cas no
The CAS Registry Mumber 497265-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,2,6 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 497265-22:
(8*4)+(7*9)+(6*7)+(5*2)+(4*6)+(3*5)+(2*2)+(1*2)=192
192 % 10 = 2
So 497265-22-2 is a valid CAS Registry Number.

, p. 287 - 291 (2007/10/03)
We have developed a method for the synthesis of ethyl 4-(3-pyridyl)- and 4-(4-pyridyl)-2-oxobutenoates by condensation of 3-pyridinecarbaldehyde and 4-pyridinecarbaldehyde monohydrate respectively with ethyl pyruvate, esterifiction of the target acids, and hydrolysis of the corresponding ethyl ester ketals in the presence of FeCl3·6H2O.
