Check Digit Verification of cas no

The CAS Registry Mumber 258826-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,8,2 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 258826-32:
(8*2)+(7*5)+(6*8)+(5*8)+(4*2)+(3*6)+(2*3)+(1*2)=173
173 % 10 = 3
So 258826-32-3 is a valid CAS Registry Number.

Efficient method for the synthesis of bisaminoethanethiols and their pyrrole conjugates

Li, Guolin,Ma, Qinggago,Ma, Bing,Grossman, Zachary D.,Pandey, Ravindra K.

, p. 2849 - 2854 (2007/10/03)

By following the protection and deprotection approach, an efficient method for the preparation of bisaminoethanethiol ligands (N2S2) is discussed. In our attempts to synthesize certain nonpeptide analogs of neurotensin, moldel studies were performed by using these ligands for preparing the corresponding pyrrole based conjugates. This methodology provides an alternate approach for developing various target specific agents that cross the blood brain barrier.
