Check Digit Verification of cas no

The CAS Registry Mumber 401837-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,1,8,3 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 401837-93:
(8*4)+(7*0)+(6*1)+(5*8)+(4*3)+(3*7)+(2*9)+(1*3)=132
132 % 10 = 2
So 401837-93-2 is a valid CAS Registry Number.

Studies on organometallic selective estrogen receptor modulators. (SERMs) Dual activity in the hydroxy-ferrocifen series

Top, Siden,Vessières, Anne,Cabestaing, Claude,Laios, Ionna,Leclercq, Guy,Provot, Christian,Jaouen, G.érard

, p. 500 - 506 (2001)

Synthesis of 7, a ferrocene derivative of the antiestrogenic drug hydroxytamoxifen bearing a basic chain-O(CH2)nN(CH3)2 with n=4 is presented, together with both studies of its antiproliferative effect on the hormone-dependent MCF7 cell line (estrogen receptor positive cells) and of its genotoxicity. This molecule is easily prepared via a McMurry coupling reaction. The antiproliferative effect found for 7 at an incubation molarity of 1 μM was very close to that found for the usual reference molecule, namely OH-tamoxifen. In addition to its structural antiestrogenic effect, 7 showed cytotoxic activity probably due to the vectored ferrocene. This genotoxic component was confirmed by a 3D (damaged DNA detection) test, that permits identification and quantification of lesions induced on DNA. Some key interactions of 7 docked into the alpha-estrogen receptor binding site were also shown.
