Check Digit Verification of cas no

The CAS Registry Mumber 1045756-12-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,7,5 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1045756-12:
(9*1)+(8*0)+(7*4)+(6*5)+(5*7)+(4*5)+(3*6)+(2*1)+(1*2)=144
144 % 10 = 4
So 1045756-12-4 is a valid CAS Registry Number.

Synthesis and structure-activity relationship studies of cytotoxic cinnamic alcohol derivatives

Zou, Hong-Bin,Zhang, Liang,Yang, Lei-Xiang,Yang, Liu-Qing,Zhao, Yu,Yu, Yong-Ping,Stoeckigt, Joachim

, p. 203 - 221 (2011/04/15)

Three series of di- and trisubstituted derivatives of cinnamic alcohol and its conjugated dienol analogues were designed and synthesised. The derivatives were screened for cytotoxicity against nine tumour cell lines: KB, A549, Hela, CNE, PC-3, BEL-7404, HL-60, BGC823 and P388D1. Most of the cinnamic alcohol derivatives showed cytotoxic activity. The compound 7-(4',5'-dichlorobenzyloxy)- 6,8-dihydroxycinnamic alcohol (55) exhibited significant cytotoxicity to seven human tumour cell lines on a micromolar range, especially with regard to the KB and P388D1 cell lines, showing IC50 values of 0.4 and 0.5μ M, respectively. The structure-activity relationships of the derivatives are discussed.
