Check Digit Verification of cas no

The CAS Registry Mumber 21634-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,3 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21634-53:
(7*2)+(6*1)+(5*6)+(4*3)+(3*4)+(2*5)+(1*3)=87
87 % 10 = 7
So 21634-53-7 is a valid CAS Registry Number.

Flavonoid Constituents of Chorizanthe diffusa with Potential Cancer Chemopreventive Activity

Chung, Ha Sook,Chang, Leng Chee,Lee, Sang Kook,Shamon, Lisa A.,Breemen, Richard B. van,et al.

, p. 36 - 41 (1999)

An ethyl acetate-soluble extract of Chorizanthe diffusa was found to exhibit significant antioxidant activity, as judged by scavenging stable 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals and inhibition of 12-O-tetradecanoylphorbol 13-acetate (TPA)-i
