Check Digit Verification of cas no
The CAS Registry Mumber 656233-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,2,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 656233-40:
(8*6)+(7*5)+(6*6)+(5*2)+(4*3)+(3*3)+(2*4)+(1*0)=158

, p. 5592 - 5599 (2005)
We have synthesized a conjugate of cis-4,7,10,13,16,19-docosahexenoic acid (DHA) and 10-hydroxycamptothecin (HCPT), DHA-HCPT. The antitumor activity of DHA-HCPT was evaluated in vitro against L1210 leukemia cells and in experimental animal tumor models in
