Check Digit Verification of cas no

The CAS Registry Mumber 1456716-75-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,6,7,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1456716-75:
(9*1)+(8*4)+(7*5)+(6*6)+(5*7)+(4*1)+(3*6)+(2*7)+(1*5)=188
188 % 10 = 8
So 1456716-75-8 is a valid CAS Registry Number.

Efficient synthesis of 1,4-disubstituted triazolyl N-carboxamides via a simple and convenient MCR using basic alumina as solid support

Pal, Rammyani,Sarkar, Swarbhanu,Chatterjee, Nivedita,Sen, Asish Kumar

, p. 5642 - 5646 (2013/09/23)

A microwave assisted green protocol for the synthesis of 1,4-disubstituted triazolyl N-carboxamides was explored using basic alumina as solid support. The method allows domino Ullmann-type reaction, Click reaction and formation of ester or amide linkages in a single reaction vessel using Cu(phen)(PPh 3)Br and CMPA as catalyst and basic alumina as solid support in high yield. The protocol did not require addition of any external ligands or base. The method was also found to be equally good for the synthesis of bis triazole adducts.
