21938-64-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21938-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21938-64:
(7*2)+(6*1)+(5*9)+(4*3)+(3*8)+(2*6)+(1*4)=117
117 % 10 = 7
So 21938-64-7 is a valid CAS Registry Number.

Microwave-assisted one-pot three-component synthesis of thiazolidinones using KSF@Ni as an efficient heterogeneous catalyst

Mahmoodi, Nosrat O.,Mohammadgholipour, Samane,Ghanbari Pirbasti, Fateme

, p. 668 - 678 (2017)

Convenient, one-pot three-component reaction for the synthesis of thiazolidinones from aldehydes, thiosemicarbazide, and maleic anhydride in the presence of KSF@Ni as heterogeneous catalyst under microwave irradiation was developed. Products were obtained

Baker's yeast catalyzed one-pot synthesis of bioactive 2-[benzylidene(or pyrazol-4-ylmethylene)hydrazono]-1,3-thiazolidin-4-one-5-yl-acetic acids

Chavan, Anusaya S.,Kharat, Arun S.,Bhosle, Manisha R.,Mane, Ramrao A.

, p. 103 - 107 (2018/04/25)

An efficient and simple one-pot protocol has been developed for synthesis of substituted derivatives of 2-hydrazono-4-thiazolidinone-5-acetic acids 4a-j and 6a-g by cyclocondensation of aryl/pyrazolyl aldehyde, thiosemicarbazide and maleic anhydride in acetonitrile in the presence of readily available whole cell biocatalyst, baker's yeast (Saccharomyces cerevisiae). The reaction is enhanced by ultrasonication.
