Check Digit Verification of cas no
The CAS Registry Mumber 53003-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,0,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 53003-18:
(7*5)+(6*3)+(5*0)+(4*0)+(3*3)+(2*1)+(1*8)=72
72 % 10 = 2
So 53003-18-2 is a valid CAS Registry Number.

The natural alkaloid, tryptanthrin (indolo[2,1-b]quinazoline-6,12-dione), and its analogues are found to exhibit potent antitumor and anti-MRSA activities. An efficient and convenient method has been developed for the synthesis of tryptanthrin D-ring derivatives through the reaction of substituted tryptanthrins and secondary amines in moderate to good yields. Some of the new compounds exhibited antitumor activities against the human tumor cell lines A549, HCT116 and MDA-MB-231, with mean IC50 values at low micromolar levels. In addition, some of the compounds showed excellent anti-MRSA activities and were more effective than vancomycin, with MIC values of 0.31–1.25 μg/mL for Mu50,RN4220, and Newman strains.
