Check Digit Verification of cas no

The CAS Registry Mumber 658041-32-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,8,0,4 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 658041-32:
(8*6)+(7*5)+(6*8)+(5*0)+(4*4)+(3*1)+(2*3)+(1*2)=158
158 % 10 = 8
So 658041-32-8 is a valid CAS Registry Number.

Synthesis and study of some properties of 1-aryl-2-oxo-1,2,3,6- tetrahydro[1,4]diazepino[6,5-b]indole 4-oxides

Ryabova,Rastorgueva,Lisitsa,Alekseeva,Granik

, p. 1386 - 1398 (2003)

A number of 1-aryl-2-oxo-1,2,3,6-tetrahydro[1,4]diazepirio[6,5-b]indole 4-oxides were synthesized based on 3-[N-aryl-N-(chloroacetyl)amino]-2- formylindoles. The nature of the substituent in the 1-aryl fragment has a pronounced influence on the course of reactions throughout the whole sequence of transformations during the synthesis of diazepinoindoles. The reduction of 4-oxides by formamidinosulfinic acid, hydrogen in the presence of Pd/C, and sodium bisulfite was studied. The structures of the reaction products were confirmed using IR and 1H NMR spectroscopy and mass spectrometry.
