220299-54-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 220299-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,9 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220299-54:
(8*2)+(7*2)+(6*0)+(5*2)+(4*9)+(3*9)+(2*5)+(1*4)=117
117 % 10 = 7
So 220299-54-7 is a valid CAS Registry Number.

Synthesis and biological activities of the marine bryozoan alkaloids convolutamines A, C and F, and lutamides A and C

Hashima, Hirofumi,Hayashi, Masahiko,Kamano, Yoshiaki,Sato, Nobuhiro

, p. 1757 - 1766 (2007/10/03)

Synthesis of convolutamines and lutamides, new 2,4,6-tribromo-3-methoxyphenethylamine alkaloids isolated from Floridian marine bryozoan Amathia convoluta, was accomplished by a sequence of reactions starting from 3-hydroxyphenethylamines. Cytotoxities of the synthetic lutamides, convolutamines and their de-O-methyl derivatives were examined using drug-sensitive and -resistant P388 as well as KB cell lines. The bioassay suggests that the 2,4,6-tribromo-3-methoxyphenethylamine is an indispensable unit for detection of the activities. Additionally, a reversal of drug resistance by those alkaloids is recognized. Copyright (C) 2000 Elsevier Science Ltd.
