Check Digit Verification of cas no

The CAS Registry Mumber 293756-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,5 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 293756-94:
(8*2)+(7*9)+(6*3)+(5*7)+(4*5)+(3*6)+(2*9)+(1*4)=192
192 % 10 = 2
So 293756-94-2 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.
