Check Digit Verification of cas no

The CAS Registry Mumber 350609-88-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,6,0 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 350609-88:
(8*3)+(7*5)+(6*0)+(5*6)+(4*0)+(3*9)+(2*8)+(1*8)=140
140 % 10 = 0
So 350609-88-0 is a valid CAS Registry Number.

Synthetic analogues of naturally occurring spider toxins: Synthesis of 2-(Hydroxyphenyl)propanamides of spermidine and spermine

Popaj, Kasim,Guggisberg, Armin,Hesse, Manfred

, p. 797 - 816 (2007/10/03)

In a study on structure-activity relationships of spider toxins, six model compounds, namely the spermidine derivatives 6, 8, and 16 as well as the spermine derivatives 24, 27, and 32 were synthesized. The synthesis proceeds through stepwise construction of the polyamine backbone, including protection and deprotection of the amino functions. The differentiation of the derivatives by analytical and spectroscopic methods is discussed.
