Check Digit Verification of cas no

The CAS Registry Mumber 181270-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,7 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 181270-85:
(8*1)+(7*8)+(6*1)+(5*2)+(4*7)+(3*0)+(2*8)+(1*5)=129
129 % 10 = 9
So 181270-85-9 is a valid CAS Registry Number.

New 2-benzylsulfanyl-nicotinic acid based 1,3,4-oxadiazoles: Their synthesis and biological evaluation

Patel, Navin B.,Purohit, Amit C.,Rajani, Dhanji P.,Moo-Puc, Rosa,Rivera, Gildardo

, p. 677 - 687 (2013/05/09)

A novel series of 5-(2-benzylsulfanyl-pyridin-3-yl)-2-(substituted)- sulfanyl-1,3,4-oxadiazoles 6a-j were synthesized from key intermediate 5-(2-benzylsulfanyl-pyridin-3-yl)-3H-[1,3,4]oxadiazole-2-thione 5. Nucleophilic substitution reactions with differe

Synthesis and antitumor activities of novel 1,4-substituted phthalazine derivatives

Zhang, Shu Lan,Liu, Ya Jing,Zhao, Yan Fang,Guo, Qiu Ting,Gong, Ping

scheme or table, p. 1071 - 1074 (2011/10/05)

A series of 1,4-substituted phthalazine derivatives were designed and synthesized. All the prepared compounds were screened for their cytotoxic activities against A549, HT-29 and MDA-MB-231 cell lines in vitro. Among them, compounds 7a-7h showed excellent selectivity for MDA-MB-231 cell line with IC50 values from 1nmol/L to 0.92μmol/L. A preliminary SAR study of these derivatives was performed.
