Check Digit Verification of cas no

The CAS Registry Mumber 1257415-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,1 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257415-40:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*1)+(3*5)+(2*4)+(1*0)=149
149 % 10 = 9
So 1257415-40-9 is a valid CAS Registry Number.

Antitumor agents 286. Design, synthesis, and structure-activity relationships of 3'R,4'R -disubstituted-2',2'-dimethyldihydropyrano[2,3- f ]chromone (DSP) analogues as potent chemosensitizers to overcome multidrug resistance

Zhou, Ting,Shi, Qian,Bastow, Kenneth F.,Lee, Kuo-Hsiung

experimental part, p. 8700 - 8708 (2011/02/23)

In this study, various 3'R,4'R-disubstituted-2'2'-dimethydihydropyrano[2,3- f]chromone (DSP) derivatives were discovered as potent chemosensitizers in the treatment of multidrug resistant cancer cells. Twenty-four DSP analogues (5-28) were synthesized and
