Check Digit Verification of cas no
The CAS Registry Mumber 20191-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,9 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20191-91:
(7*2)+(6*0)+(5*1)+(4*9)+(3*1)+(2*9)+(1*1)=77
77 % 10 = 7
So 20191-91-7 is a valid CAS Registry Number.

Catalytic oxidation of homoallylalcohols to α-alkoxytetrahydrofurans by a Pd-nitro complex and molecular oxygen
Meulemans, Tom M.,Kiers, Niklaas H.,Feringa, Ben L.,Van Leeuwen, Piet W. N. M.
, p. 455 - 458 (2007/10/02)
Various homoallylalcohols were highly regioselective oxidized with molecular oxygen at the terminal carbon to afford cyclic acetals (α-alkoxytetrahydrofurans) using PdNO2CL(CH3CN)2 as catalyst in the presence of CuCL2 and t-butanol or isopropanol.
