Check Digit Verification of cas no

The CAS Registry Mumber 1244549-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,4,5,4 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1244549-52:
(9*1)+(8*2)+(7*4)+(6*4)+(5*5)+(4*4)+(3*9)+(2*5)+(1*2)=157
157 % 10 = 7
So 1244549-52-7 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of novel 1,3,4-oxadiazolyl-quinazolin- 4(3H)ones

Patel, Navin B.,Patel, Jaymin C.

experimental part, p. 923 - 931 (2010/11/04)

A series of 1,3,4-oxadiazolyl-quinazolin-4(3H)ones have been synthesized using known methods. All the compounds have been established on basis of elemental analysis, IR and NMR spectral data. The in vitro antimicrobial screening of the synthesized compounds were carried out against two gram-positive bacteria (S. aureus, S. pyogenes), two gram-negative bacteria (E. coli, P. aeruginosa), and three fungal species (C. albicans, A. niger, A. clavatus) using the broth microdilution method. The compounds 7d, 7g, 7l, 7o, 7p, and 7r possessed pronounced antibacterial activity whereas compound 7p exhibited promising antifungal activity.
