Check Digit Verification of cas no
The CAS Registry Mumber 16539-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,3 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16539-92:
(7*1)+(6*6)+(5*5)+(4*3)+(3*9)+(2*9)+(1*2)=127
127 % 10 = 7
So 16539-92-7 is a valid CAS Registry Number.

, p. 716 - 719 (2013/05/08)
Diazo coupling reactions of aromatic amines with 2-naphthol in a green, efficient and easy procedure is described. Ferric hydrogensulfate catalyses this reaction in water at room temperature and short reaction time with high yields. The antibacterial activities of the synthesized compounds against four pathogenic bacteria are also investigated.
