261630-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 261630-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,6,3 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 261630-89:
(8*2)+(7*6)+(6*1)+(5*6)+(4*3)+(3*0)+(2*8)+(1*9)=131
131 % 10 = 1
So 261630-89-1 is a valid CAS Registry Number.

Synthesis, antibacterial, antielastase, antiurease and antioxidant activities of new methoxy substitued bis-1,2,4-triazole derivatives

Sokmen, Bahar Bilgin,Gumrukcuoglu, Nurhan,Ugras, Serpil,Ugras, Halil Ibrahim,Yanardag, Refiye

, p. 72 - 77 (2013)

The methoxy substitued two novel bis triazole-schiff bases (6 a-b) were synthesized with 4-amino-3,5-diethyl-4H-1,2,4-triazole and various bis-aldehydes. Their amine derivatives prepared by reduced with NaBH4 (5 a-b). The obtained products 6 a-b and 7 a-b were identified by FT-IR, H-NMR, 13C-NMR. The bis triazole-schiff bases and amine derivatives were tested for antimicrobial activity using the agar diffusion technique against 11 bacteria. The synthesized compounds (6 a-b and 7 a-b) were screened for their antielastase, antiurease and antioxidant activities. The resuts showed that the synthesized compounds (6 a-b and 7 a-b) had effective antielastase and antiurease activities.
