Check Digit Verification of cas no

The CAS Registry Mumber 1413441-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,3,4,4 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1413441-91:
(9*1)+(8*4)+(7*1)+(6*3)+(5*4)+(4*4)+(3*1)+(2*9)+(1*1)=124
124 % 10 = 4
So 1413441-91-4 is a valid CAS Registry Number.

Synthesis of a novel series of (E, E)-4,6-bis(styryl)-2-O-glucopyranosyl- pyrimidines and their potent multidrug resistance (MDR) reversal activity against cancer cells

Gao, Lei,Liu, Qian,Ren, Sumei,Wan, Shengbiao,Jiang, Tao,Wong, Iris L. K.,Chow, Larry M. C.,Wang, Shixi

, p. 620 - 633 (2012)

A novel series of methoxy or benzyloxy substituted (E,E)-4,6-bis(styryl)-2- O-glucopyranosyl-pyrimidines as curcuminoid analogs were synthesized in four steps with total yields of 21.5% to 33.9%. A549 and HL60 cells were employed for the anticancer activity testing. The results demonstrated that 5a, 5c, and 5e have some inhibitory activity against the HL-60 cell line. Unfortunately, no compound displayed inhibitory activity against A549 except for 5c. MDR reversal activity results demonstrated that compounds 4a (RF = 12.3) and 4b (RF = 18.5) showed strong reversal activity to the P-gp-mediated LCC6MDR cells compared to verapamil (RF = 3.2) and no cytotoxicity to cancer or normal cell lines even at a high concentrations (100M).
