Check Digit Verification of cas no

The CAS Registry Mumber 20408-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,0 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20408-22:
(7*2)+(6*0)+(5*4)+(4*0)+(3*8)+(2*2)+(1*2)=64
64 % 10 = 4
So 20408-22-4 is a valid CAS Registry Number.

Stereochemical Studies on Some vic-Bisphosphonates

Blackburn, G. Michael,Forster, Alan R.,Guo, Mao-Jun,Taylor, Graham E.

, p. 2867 - 2872 (2007/10/02)

The erythro- and racemic threo-forms of tetramethyl 1,2-dihydroxyethane-1,2-diylbisphosphonate have been identified and characterised by NMR analysis of their 2-ethoxy-1,3-dioxolane derivatives and by their independent conversion into tetramethyl cis- and trans-ethene-1,2-diylbisphosphonates respectively.Optimal conditions for the partial cis-reduction of tetraethyl ethyne-1,2-diylbisphosphonate have been identified.NMR data for the AA'XX' spectra of this range of two-carbon gem- and vic-bisphosphonates are provided and discussed.
