Check Digit Verification of cas no

The CAS Registry Mumber 1314864-59-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,8,6 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1314864-59:
(9*1)+(8*3)+(7*1)+(6*4)+(5*8)+(4*6)+(3*4)+(2*5)+(1*9)=159
159 % 10 = 9
So 1314864-59-9 is a valid CAS Registry Number.

Antifungal quinazolinones from marine-derived Bacillus cereus and their preparation

Xu, Zhihong,Zhang, Yapeng,Fu, Haichao,Zhong, Huimin,Hong, Kui,Zhu, Weiming

, p. 4005 - 4007 (2011/08/06)

Two new quinazolinones alkaloids, R(+)-2-(heptan-3-yl)quinazolin-4(3H)-one (1) and (2R,3′R)+(2S,3′R)-2-(heptan-3-yl)-2,3-dihydroquinazolin- 4(1H)-one (2) (a pair of epimers), as well as seven known analogues, 2-methylquinazolin-4(3H)-one (3), 2-benzylquinazolin-4(3H)-one (4), cyclo-(Pro-Ile), cyclo-(Pro-Leu), cyclo-(Pro-Val), cyclo-(Pro-Phe), and cyclo-(Tyr-Pro) were isolated from the n-butyl alcohol extract of the marine-derived bacterium Bacillus cereus 041381. The new compounds were identified by spectroscopic analysis and chemical synthesis. Four optical isomers 5-8 were also synthesized. Compounds 1-8 all showed moderate antifungal activity against Candida albicans with MIC values of 1.3-15.6 μM. Compound 5 exhibits the most powerful antifungal activity, which may reveal that S-configuration and 2,3-double bond were necessary for antifungal activity, and the racemization at C-2 and C-3′ reduced the antifungal activity.
