Check Digit Verification of cas no

The CAS Registry Mumber 21817-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,1 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21817-49:
(7*2)+(6*1)+(5*8)+(4*1)+(3*7)+(2*4)+(1*9)=102
102 % 10 = 2
So 21817-49-2 is a valid CAS Registry Number.

P-tert-Butylcalix[8]arene catalysed synthesis of 3,5-dinitrothiophene scaffolds: Antiproliferative effect of some representative compounds on selective anticancer cell lines

Sarkar, Piyali,Maiti, Samares,Ghosh, Krishnendu,Sengupta, Sumita,Butcher, Ray J.,Mukhopadhyay, Chhanda

supporting information, p. 996 - 1001 (2014/02/14)

A new efficient protocol for the synthesis of 3,5-dinitrothiophene scaffolds was developed by using simple p-tert-butylcalix[8]arene in aqueous medium. Biological activities of some representative compounds were also studied to inhibit the cell growth on selective anticancer cell lines.

Catalysis in Aromatic Nucleophilic Substitution. Part 9. Kinetics of the Reactions of 2-Bromo-3,5-dinitrothiophene with Some meta- and para-Substituted Anilines in Benzene

Arnone, Caterina,Consiglio, Giovanni,Spinelli, Domenico,Frenna, Vincenzo

, p. 2153 - 2156 (2007/10/02)

The rate constants of debromination of 2-bromo-3,5-dinitrothiophene by various meta-and para-substituted anilines have been measured in benzene at 25 deg C.The reactions are mildly accelerated by increasing the amine concentration, showing 'low' kB/
