Check Digit Verification of cas no

The CAS Registry Mumber 204764-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,7,6 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204764-72:
(8*2)+(7*0)+(6*4)+(5*7)+(4*6)+(3*4)+(2*7)+(1*2)=127
127 % 10 = 7
So 204764-72-7 is a valid CAS Registry Number.

Synthesis and cytotoxic activity of novel 10-alkylated docetaxel analogs

Nakayama, Kiyoshi,Terasawa, Hirofumi,Mitsui, Ikuo,Ohsuki, Satoru,Uoto, Kouichi,Iimura, Shin,Soga, Tsunehiko

, p. 427 - 432 (2007/10/03)

An alkylation method of docetaxel at the C-10 position has been established by a radical coupling reaction using a 10-xanthate derivative of 7-O-TES-10-deacetylbaccatin III and appropriate alkenes. In addition the cytotoxic activity of 10-alkylated docetaxel analogs was evaluated. Among these analogs, a derivative having a methoxycarbonyl group at the end of the alkyl moiety exhibited more potent cytotoxic activity than docetaxel.
