Check Digit Verification of cas no

The CAS Registry Mumber 202519-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,5,1 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 202519-82:
(8*2)+(7*0)+(6*2)+(5*5)+(4*1)+(3*9)+(2*8)+(1*2)=102
102 % 10 = 2
So 202519-82-2 is a valid CAS Registry Number.

Synthesis and some properties of 4-alkyl-5-cyano-6-mercapto-3,4-dihydropyridin-2(1H)-ones

Dyachenko,Krivokolysko,Litvinov

, p. 1912 - 1915 (1997)

Condensation of propionic (or acetic) aldehyde, cyanothioacetamide, Meldrum's acid, and N-methylmorpholine occurs via the intermediate formation of the corresponding Michael adducts and yields 4-alkyl-5-cyano-6-mercapto-3,4-dihydropyridin-2(1H)-ones. The oxidation of the reaction products with DMSO and their alkylation were studied.
