Check Digit Verification of cas no

The CAS Registry Mumber 83514-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,1 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83514-42:
(7*8)+(6*3)+(5*5)+(4*1)+(3*4)+(2*4)+(1*2)=125
125 % 10 = 5
So 83514-42-5 is a valid CAS Registry Number.

NEW METHOD OF SYNTHESIS OF QUINDOLINES FROM 1,5-DIKETONES OF THE INDOLINONE SERIES

Sevodin, V. P.,Velezheva, V. S.,Erofeev, Yu. V.,Suvorov, N. N.

, p. 1374 - 1380 (2007/10/02)

By the action of ammonium acetate and α,β-unsaturated carbonyl compounds, 1,5-diketones of the indolinone series undergo not yet known transformations into difficulty accessible 1,2-dihydro-10H-quindolines.Under these conditions, 11-phenyl-1,2,3,4-tetrahydro-10H-quindoline was obtained from 1-acetyl-2-(benzylcyclohexan-1-on-α-yl)indolin-3-one.Dihydroquindolines with identical aryl substituents in the 1- and 11-positions were obtained from 1-acetylindolin-3-one by the action of an excess of certain α,β-unsaturated ketones and ammonium acetate.Dehydrogenation ofdihydroquindolines proceeds smoothly on heating with sulfur.The possible paths of the formation of dihydroquindolines are discussed.
