Check Digit Verification of cas no

The CAS Registry Mumber 256934-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,9,3 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 256934-83:
(8*2)+(7*5)+(6*6)+(5*9)+(4*3)+(3*4)+(2*8)+(1*3)=175
175 % 10 = 5
So 256934-83-5 is a valid CAS Registry Number.

A series of indole containing oxazolines has been discovered as a result of structural modifications of the lead compound A-105972. The compounds exert their anticancer activity through inhibition of tubulin polymerization by binding at the colchicine site. A-289099 was identified as an orally active antimitotic agent active against various cancer cell lines including those that express the MDR phenotype. The anticancer activity, pharmacokinetics, and an efficient and enantioselective synthesis of A-289099 are described.
