Check Digit Verification of cas no
The CAS Registry Mumber 18476-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,7 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18476-18:
(7*1)+(6*8)+(5*4)+(4*7)+(3*6)+(2*1)+(1*8)=131
131 % 10 = 1
So 18476-18-1 is a valid CAS Registry Number.

EVIDENCE IN SUPPORT OF TETRAOXASPIROPHOSPHORANE INTERMEDIATES WITH A SIX-MEMBERED RING AND A P-H BOND IN INTRAMOLECULAR TRANSESTERIFICATION REACTIONS
Lier, Johan J. C. Van,Hermans, Rob J. M.,Buck, Henk M.
, p. 173 - 188 (2007/10/02)
Preparation of tetraoxaspirophosphorane 5 via two possible routes, starting from the isomeric P(V) precursors 10 and 11 results in identical 31P NMR spectra indicative of various P(III) compounds.By analysis of the products and application of low-temperature 31P NMR techniques it is shown that the phosphorane 5 is involved as an intermediate in the intramolecular transesterification 10 ->//- 28 which rules out spirophosphorane 7.These results are rationalized on the basis of orientation effects and Pearson's HASB theory.
