Check Digit Verification of cas no

The CAS Registry Mumber 1234564-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,5,6 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1234564-31:
(9*1)+(8*2)+(7*3)+(6*4)+(5*5)+(4*6)+(3*4)+(2*3)+(1*1)=138
138 % 10 = 8
So 1234564-31-8 is a valid CAS Registry Number.

Efficient synthesis and identification of novel propane-1,3-diamino bridged CCR5 antagonists with variation on the basic center carrier

Fan, Xing,Zhang, Hu-Shan,Chen, Li,Long, Ya-Qiu

experimental part, p. 2827 - 2840 (2010/08/22)

By employing pharmacophore-based design and the privileged fragments reassembly, a series of piperidine-/tropane-/piperazine-bridged CCR5 antagonists were designed and synthesized via an efficient convergent synthesis strategy, with focus on the optimal choice of the basic center carrier structure. Significantly, the 4-amino-4-methylpiperidine bridged 1-acyl-1,3-propanediamine compounds were identified as a new class of nanomolar CCR5 antagonists, providing an efficient approach and novel scaffolds for further development of potent CCR5 inhibitors.
