Check Digit Verification of cas no

The CAS Registry Mumber 195875-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,8,7 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195875-00:
(8*1)+(7*9)+(6*5)+(5*8)+(4*7)+(3*5)+(2*0)+(1*0)=184
184 % 10 = 4
So 195875-00-4 is a valid CAS Registry Number.

A new type of fluorescence labeling of nucleosides, nucleotides and oligonucleotides

Sigmund, Harald,Maier, Thomas,Pfleiderer, Wolfgang

, p. 685 - 696 (1997)

Fluorescein has been coupled to the amino groups of the common nucleosides via a carbamoyl spacer to form a new type of conjugates. The corresponding phosphoramidites have been prepared with Npe and Npeoc protecting groups for application in oligonucleotide synthesis. Hybridizations have been studied in dependence of the fluorescing label as well as fluorescence quantum yields and fluorescence anisotropy effects.
