Check Digit Verification of cas no

The CAS Registry Mumber 1084789-69-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,4,7,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1084789-69:
(9*1)+(8*0)+(7*8)+(6*4)+(5*7)+(4*8)+(3*9)+(2*6)+(1*9)=204
204 % 10 = 4
So 1084789-69-4 is a valid CAS Registry Number.

PREPARATION OF 3-SUBSTITUTED QUINOLINES. II. PREPARATION AND CYCLODEHYDRATION OF α-ALKYL- AND α-PHENYL-β-ARYLAMINOACROLEIN DERIVATIVES

Todoriki, Reiko,Ono, Machiko,Tamura, Shinzo

, p. 755 - 769 (2007/10/02)

α-Methyl-β-arylaminoacroleins were prepared by the hydrolysis of 2-methyl-1-arylamino-3-arylimino-1-propene derivatives. α-Ethyl- and α-phenyl-β-arylaminoacroleins were prepared by the reaction of arylamine and 2-substituted 1,1,3,3-tetraethoxypropane derivatives. 3-Methyl, 3-ethyl- and 3-phenylquinolines were obtained from α-methyl-, α-ethyl and α-phenyl-β-arylaminoacroleins on heating with aluminum bromide in good yields. α-Bromo-β-anilinoacrolein (9b) was prepared by the reaction of β-anilinoacrolein (6b) and N-bromosuccinimide.Reaction of 9b and aluminum bromide did not afford 3-bromoquinoline.
