Check Digit Verification of cas no

The CAS Registry Mumber 89723-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89723-19:
(7*8)+(6*9)+(5*7)+(4*2)+(3*3)+(2*1)+(1*9)=173
173 % 10 = 3
So 89723-19-3 is a valid CAS Registry Number.

Chemistry of Thienopyridines. XXX. Elaboration of the Substituent in 6-Cyanothienopyridine

Klemm, L. H.,Muchiri, Daniel R.

, p. 1717 - 1719 (2007/10/02)

Ten derivatives of thienopyridine bearing substituents at the 6-position are obtained from transformations which start with 6-cyanothienopyridine (2).Treatment of 2 with sodium alkoxide-alkanol gives imidates (3) in ca. 85percent yield.Methyl imidate 3a reacts, in turn, with ammonium chloride to produce a carboxamidine (84percent), with 1,ω-alkyldiamines to form cyclic amidines, and with Meldrum's acid to give an aminoester intermediate (4) (36percent).Various reagents then convert 4 into the acetyl derivative (86percent) (also obtained directly from 2), an unsaturated aminoester (6) (80percent), and a β-ketoester (7) (36percent).Spectral data are reported for zthese compounds.
