Check Digit Verification of cas no

The CAS Registry Mumber 1190084-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,0,8 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1190084-55:
(9*1)+(8*1)+(7*9)+(6*0)+(5*0)+(4*8)+(3*4)+(2*5)+(1*5)=139
139 % 10 = 9
So 1190084-55-9 is a valid CAS Registry Number.

Synthesis of 4-hydroxy-3-formylideneamino-lH/methyl/phenylquinolin-2-ones

Bhudevi,Ramana,Mudiraj, Anwita,Reddy

experimental part, p. 255 - 260 (2009/12/03)

An efficient method for the synthesis of 4-hydroxy-3-formylideneamino-l H/methyl/phenylquinolin-2-ones by the condensation of corresponding 4-hydroxy-3-formyl-l///methyl/phenylquinolin-2-one with substituted anilines/aliphatic primary amines is reported. The carboxaldehyde in turn is prepared starting either from substituted anilines or benzoic acid. The structures of compounds are established by the elemental analysis and spectral data.
