69999-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69999-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,9 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 69999-67:
(7*6)+(6*9)+(5*9)+(4*9)+(3*9)+(2*6)+(1*7)=223
223 % 10 = 3
So 69999-67-3 is a valid CAS Registry Number.

Stereoselective synthesis of (+)-Δ5-dehydrosugiyl methyl ether
Li,Peng,Bie,Wu,Pan,Yang
, p. 328 - 329 (2007/10/03)
A stereoselective synthetic route to (+)-Δ5-dehydrosugiyl methyl ether 1 was developed from (S)-(-)-α-cyclocitral 6 in which DDQ as a better oxidant for enone was used.
