164668-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 164668-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,6,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 164668-41:
(8*1)+(7*6)+(6*4)+(5*6)+(4*6)+(3*8)+(2*4)+(1*1)=161
161 % 10 = 1
So 164668-41-1 is a valid CAS Registry Number.

An expeditious enantiospecific total synthesis of (+)-7-epi-goniofufurone

Prasad, Kavirayani R.,Gholap, Shivajirao L.

, p. 2260 - 2262 (2005)

Stereoselective synthesis of styryl lactone, (+)-7-epi-goniofufurone was achieved in high yield via simple transformations from tartaric acid. The key step involves the successive stereoselective reduction of ketones with borohydride and selectride. Georg

Stereoselective total synthesis of bioactive styryllactones: 9-Deoxygoniopypyrone, goniopypyrone and 7-epi-goniofufurone

Prasad, Kavirayani R.,Dhaware, Madhuri G.

, p. 3697 - 3705 (2008/09/19)

Stereoselective synthesis of the bioactive styryllactones (+)-9-deoxygoniopypyrone, (+)-goniopypyrone and (+)-7-epi-goniofufurone has been achieved from D-(-)-tartaric acid. The key step involves the elaboration of a trihydroxy ester to the title compound

Enantiospecific Syntheses of (+)-Goniofufurone, (+)-7-epi-Goniofufurone, (+)-Goniobutenolide A, (-)-Goniobutenolide B, (+)-Goniopypyrone, (+)-Altholactone, (+)-Goniotriol, and (+)-7-Acetylgoniotriol

Shing, Tony K. M.,Tsui, Hon-Chung,Zhou, Zhao-Hui

, p. 3121 - 3130 (2007/10/02)

Practical and efficient syntheses of a number of styryl lactones with various structural complexities were accomplished from commercially available and inexpensive D-glycero-D-gulo-heptono-γ-lactone (D-glucoheptonic γ-lactone) (11).Lactone 11 was converte
