Check Digit Verification of cas no

The CAS Registry Mumber 139557-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,5 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139557-71:
(8*1)+(7*3)+(6*9)+(5*5)+(4*5)+(3*7)+(2*7)+(1*1)=164
164 % 10 = 4
So 139557-71-4 is a valid CAS Registry Number.

A propeller-like small molecule as a novel G-quadruplex DNA binder: The study of fluorescent sensing property and preferential interactions with human telo21 structure

Sun, Ning,Li, Dongli,Hou, Jinqiang,Long, Wei,Guo, Qi,Lu, Yujing,Zhang, Kun,Yuan, Wenchang,Wong, Wing-Leung

, p. 979 - 985 (2019)

A new propeller-like small molecule was synthesized with three terminal amino side groups. The molecule was found to be a selective nucleic acid binder towards telo21 G-quadruplex DNA compared with other representative nucleic acids including single-stran

Synthesis and Characterization of Mono-, Bis-, and Trissubstituted Pyridinium and Pyrylium Dyes

Matsui, Masaki,Kawamura, Shigeo,Shibata, Katsuyoshi,Muramatsu, Hiroshige

, p. 71 - 74 (2007/10/02)

A series of mono-, bis-, and trissubstituted pyridinium and pyrylium dyes have been synthesized by the condensation of methylpyridinium and methylpyrylium salts with aldehydes or nitroso compound.Large bathochromic shifts were observed in the following order, both in substituted azomethine pyridinium and pyrylium dyes, monobistris.The magnitude of the shift appeared in the order of multiple bonds, -CH=CH- -CH=CH- CH=CH- -CH=N-.
