Check Digit Verification of cas no
The CAS Registry Mumber 103763-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,6 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103763-39:
(8*1)+(7*0)+(6*3)+(5*7)+(4*6)+(3*3)+(2*3)+(1*9)=109
109 % 10 = 9
So 103763-39-9 is a valid CAS Registry Number.

A NEW ROUTE TO 1-OXYGENATED CARBAZOLES. SYNTHESIS OF MURRAYAFOLINE-A
Martin, Tracey,MoodY, Christopher J.
, p. 5841 - 5842 (1985)
1-Oxygenated carbazoles are prepared in four steps from indole-2-carboxylates by Claisen condensation with butyrolactones, followed by hydrolysis with concomitant decarboxylation, oxidation, and ring closure (Scheme 2); the route is applied to the synthes
