Check Digit Verification of cas no

The CAS Registry Mumber 97669-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,6 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97669-55:
(7*9)+(6*7)+(5*6)+(4*6)+(3*9)+(2*5)+(1*5)=201
201 % 10 = 1
So 97669-55-1 is a valid CAS Registry Number.

SYNTHESIS OF 3-CYANO-4-ARYL-5-ETHOXYCARBONYL-6-METHYL-3,4-DIHYDROPYRIDINE-2-THIONES

Krauze, A. A.,Liepin'sh, E. E.,Pelcher, Yu. E.,Kalme, Z. A.,Dipan, I. V.,Dubur, G. Ya.

, p. 77 - 83 (1985)

The condensation of ethyl arylideneacetoacetate with cyanothioacetamide and of arylidenecyanothioacetamides with ethyl acetoacetate or of arylidenecyanothioacetamides with ethyl β-aminocrotonate gave 3-cyano-4-aryl-5-ethoxycarbonyl-6-methyl-3,4-dihydropyridine-2-thiones.PMR spectroscopy showed that the 3-cyano-4-aryl-3,4-dihydropyridine-2-thiones are formed as a mixture of cis and trans isomers.
