30991-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30991-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,9 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30991-44:
(7*3)+(6*0)+(5*9)+(4*9)+(3*1)+(2*4)+(1*4)=117
117 % 10 = 7
So 30991-44-7 is a valid CAS Registry Number.

, (2021/02/03)

A selective and sensitive Zn(II) ion responsive optical probe (E)-N′-(2, 4-dihydroxybenzylidene)-3, 5-di-tert-butyl-2-hydroxybenzohydrazide (L) was designed, synthesized and characterized. The optical behavior of L towards different metal ions were invest

An ESIPT blocked highly ICT based molecular probe to sense Zn (II) ion through turn on optical response: Experimental and theoretical studies

Budri, Mahantesh,Naik, Ganesh,Patil, Shivaraj,Kadolkar, Prajakta,Gudasi, Kalagouda,Inamdar, Sanjeev

, (2019/12/28)

A simple and low cost optical sensor (L) is synthesized by the condensation reaction and characterized systematically. Among the various tested metal ions, L selectively interacts with Zn2+ ion by inducing a 17-fold high fluorescence intensity
