Check Digit Verification of cas no

The CAS Registry Mumber 1221157-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,1,5 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1221157-04:
(9*1)+(8*2)+(7*2)+(6*1)+(5*1)+(4*5)+(3*7)+(2*0)+(1*4)=95
95 % 10 = 5
So 1221157-04-5 is a valid CAS Registry Number.

Abstract A total of 11 novel combretastatin A-4 (CA-4) analogs were designed, synthesized, and evaluated for the anti-proliferative effects in tumor cells. The compounds represent four structural classes: (i) hydrogenated derivatives, (ii) ethoxyl derivatives, (iii) amino derivatives and (iv) pro-drugs. Biological evaluations demonstrate that multiple structural features control the biological potency. Three of the compounds, sit-1, sit-2 and sit-3, have potent anti-proliferative activity against multiple cancer cell lines. Their pro-drugs were synthesized to increase water solubility. Structure-activity relationship study and Surflex-Docking were studied in this paper. These results will be useful for the design of new CA-4 analogs that are structurally related to the SAR study.
