Check Digit Verification of cas no

The CAS Registry Mumber 1804-52-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1804-52:
(6*1)+(5*8)+(4*0)+(3*4)+(2*5)+(1*2)=70
70 % 10 = 0
So 1804-52-0 is a valid CAS Registry Number.

Zebrafish based strategy for the identification of a potential pharmacophore for apoptosis: A greener CuAAC approach for novel 1,2,3-triazoles derived from mefenamic acid

Babu, P. Vijaya,Mukherjee, Soumita,Gorja, Dhilli Rao,Yellanki, Swapna,Medisetti, Raghavender,Kulkarni, Pushkar,Mukkanti,Pal, Manojit

, p. 4878 - 4882 (2014)

Prompted by the potential of a screening strategy in zebrafish for the identification of valuable pharmacophores, a series of triazole substituted mefenamic acid derivatives were designed and synthesized via a CuAAC under green conditions. A variety of terminal alkynes were reacted with the azide obtained from mefenamic acid to give the expected products in good to excellent yields. When screened for apoptosis, teratogenicity and hepatotoxicity in zebrafish embryos, one of these compounds showed encouraging apoptotic properties and safety profiles and seemed to have medicinal value.

Phosphonic acid analogs of diclofenac: An Arbuzov reaction of trimethylphosphite with an ortho-quinonoid intermediate

Mugrage, Ben,Diefenbacher, Clive,Somers, Joe,Parker, David T.,Parker, Tonia

, p. 2047 - 2050 (2007/10/03)

The phosphonic acid analog of the NSAID Diclofenac was efficiently synthesized via an Arbuzov reaction between 2-(2,6-dichloroanilino)benzyl alcohol and trimethyl phosphite followed by TMSBr promoted dealkylation. Seven related phosphonic acids were synth
