Check Digit Verification of cas no
The CAS Registry Mumber 279-50-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,7 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 279-50:
(5*2)+(4*7)+(3*9)+(2*5)+(1*0)=75
75 % 10 = 5
So 279-50-5 is a valid CAS Registry Number.

Trans-2,5-disubstituted tetrahydrofurans via addition of carbon nucleophiles to the strained bicyclic acetal 2,7-dioxabicyclo[2.2.1] heptane
Friestad, Gregory K.,Lee, Hye Jin
, p. 3958 - 3961 (2009)
(Figure Presented) Addition of allyltributylstannane to 2,7-dioxabicyclo[2.2.1]heptane in the presence of TiCI4 produces 5-allyl-2-(hydroxymethyl)tetrahydrofuran with a transieis ratio of 93:7. The frans-selectivity is also observed in addition
