Check Digit Verification of cas no
The CAS Registry Mumber 1042909-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,9,0 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1042909-04:
(9*1)+(8*0)+(7*4)+(6*2)+(5*9)+(4*0)+(3*9)+(2*0)+(1*4)=125
125 % 10 = 5
So 1042909-04-5 is a valid CAS Registry Number.

Stereoselective synthesis of 3-oxygenated-ds-dialkyl-2,5-substituted tetrahydrofurans from cyclohexadienediols
Brovetto, Margarita,Seoane, Gustavo
, p. 5776 - 5785 (2008/12/21)
(Chemical Equation Presented) The 3-oxygenated-cis-dialkyl-2,5-substituted tetrahydrofuran system, present in several natural products, was prepared with good selectivity by acidic cyclization of 5-alkene-1,2,4-triol derivatives. The starting alkenol was
