Check Digit Verification of cas no

The CAS Registry Mumber 503046-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 503046-89:
(8*5)+(7*0)+(6*3)+(5*0)+(4*4)+(3*6)+(2*8)+(1*9)=117
117 % 10 = 7
So 503046-89-7 is a valid CAS Registry Number.

Synthesis and biological activity of important phenolic mannich bases

Kousar, Fareeha,Nosheen, Sofia,Zahra, Sayeda Nida,Kousar, Summaira,Jahan, Nazish

, p. 59 - 62 (2013)

A series of Mannich bases were synthesized by the condensation reaction of phenols and amines in the presence of formaldehyde. The newly synthesized Mannich bases were well characterized by FT-IR spectroscopy. All the synthesized compounds were tested for their antibacterial activity against Pasturella multocida and Staphylococcus aureus. The results have shown that most of the compounds are quite active against these pathogenic bacteria.
