Check Digit Verification of cas no

The CAS Registry Mumber 83348-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,4 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83348-67:
(7*8)+(6*3)+(5*3)+(4*4)+(3*8)+(2*6)+(1*7)=148
148 % 10 = 8
So 83348-67-8 is a valid CAS Registry Number.

Synthesis of vincaminic acid derivatives

-

, (2008/06/13)

Vincaminic acid derivatives of formula (A) STR1 useful in treating cerebral insufficiency, are prepared by reacting 1-ethyl-2,3,4,6,7,12-hexahydroindolo[2,3-a]quinolizine with the 2,4-DNP hydrazone of ethyl or methyl bromopyruvate followed by (i) reduction of the C=N bond and (ii) simultaneous cyclization with removal of the ketone-protecting group in either order.
