Check Digit Verification of cas no

The CAS Registry Mumber 181823-46-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,8,2 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 181823-46:
(8*1)+(7*8)+(6*1)+(5*8)+(4*2)+(3*3)+(2*4)+(1*6)=141
141 % 10 = 1
So 181823-46-1 is a valid CAS Registry Number.

A convenient synthesis of n-substituted 2,3-dihydro-3-oxoisothiazolo[5,4-b]pyridines in acidic conditions

Terauchi, Hideo,Tanitame, Akihiko,Tada, Keiko,Nishikawa, Yoshinori

, p. 1719 - 1734 (2007/10/03)

A novel and convenient synthesis of N-substituted 2,3-dihydro-3-oxoisothiazolo[5,4-b]pyridines which possess potent in vitro inhibitory activity against gastric (H+/K+)-ATPase is reported. Compared with the methods reported previously, the compounds were synthesized more readily in relatively high yields by conversion of N-substituted 2-(benzyl-, 1-phenylethyl-, and benzhydrylsulfinyl)nicotinamides (17d-l) in a diluted hydrochloric acid-methanol solution at room temperature.
