Check Digit Verification of cas no
The CAS Registry Mumber 1670-89-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1670-89:
(6*1)+(5*6)+(4*7)+(3*0)+(2*8)+(1*9)=89
89 % 10 = 9
So 1670-89-9 is a valid CAS Registry Number.

Some Observations on the Formation of 1-Hydroxyindoles in the Leimgruber-Batcho Indole Synthesis
Clark, Robin D.,Repke, David B.
, p. 121 - 125 (2007/10/02)
The factors influencing the formation of 1-hydroxyindoles in the catalytic hydrogenation of β-dimethylamino-2-nitrostyrenes (Leimgruber-Batcho indole synthesis) have been investigated.Significant amounts of 1-hydroxyindoles were obtained only when the β-dimethylamino-2-nitrostyrene was substituted with an electron-withdrawing group at the 5 or 6 position.The proportion of 1-hydroxyindole formed relative to the normal indole product was found to increase as both the amount of catalyst and hydrogen pressure were decreased.
