76787-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76787-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,8 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76787-77:
(7*7)+(6*6)+(5*7)+(4*8)+(3*7)+(2*7)+(1*7)=194
194 % 10 = 4
So 76787-77-4 is a valid CAS Registry Number.

Novel 6,7-diphenyl-2,3,8,8a-tetrahydro-1H-indolizin-5-one analogues as cytotoxic agents

Sharma, Vedula M.,Adi Seshu,Vamsee Krishna,Prasanna,Chandra Sekhar,Venkateswarlu,Rajagopal, Sriram,Ajaykumar,Deevi, Dhanvanthri S.,Rao Mamidi,Rajagopalan

, p. 1679 - 1682 (2007/10/03)

A series of 6,7-diphenyl-2,3,8,8a-tetrahydro-1H-indolizin-5-one analogues were synthesized and evaluated for cytotoxic activity against eight human cancer cell lines. Compounds 18, 21, 28, 29, 30 and 31 showed cytotoxic activity with GI50 value

A New Synthesis of Septicine, a Secophenanthroindolizine Alkaloid

Mangla, V. K.,Bhakuni, D. S.

, p. 748 - 749 (2007/10/02)

Septicine , an alkaloid isolated from Ficus septica and Tylophora asthmatica, has been synthesized using 2-(3',4'-dimethoxyphenacyl)pyrrolidine (6) and 3,4-dimethoxy-phenylacetyl chloride (11) as the essential intermediates.Condensation of 6 and 11 affords 2-(3',4'-dimethoxyphenacyl)-N-(3'',4''-dimethoxyphenylacetyl)pyrrolidine (12) which on treatment with potassium-t-butoxide furnishes 6,7-di-(3',4'-dimethoxyphenyl)-5-oxo-1,2,3,5,8,8a-hexahydroindolizine (13).LAH reduction of 13 affords septicine (1), identical (co-TLC, IR, PMR, m.m.p.) with a natural sample.
