Check Digit Verification of cas no

The CAS Registry Mumber 269402-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,4,0 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 269402-54:
(8*2)+(7*6)+(6*9)+(5*4)+(4*0)+(3*2)+(2*5)+(1*4)=152
152 % 10 = 2
So 269402-54-2 is a valid CAS Registry Number.

Synthesis and in vitro evaluation of quaternary ammonium derivatives of chlorambucil and melphalan, anticancer drugs designed for the chemotherapy of chondrosarcoma

Giraud, Isabelle,Rapp, Maryse,Maurizis, Jean-Claude,Madelmont, Jean-Claude

, p. 2116 - 2119 (2007/10/03)

To enhance affinity for malignant cartilaginous tumors (chondrosarcomas), quaternary ammonium (QA) conjugates of chlorambucil and melphalan were prepared by linking the QA moiety to nitrogen mustards via an amide bond. They exhibited closely similar and s
