123435-97-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123435-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,3 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123435-97:
112 % 10 = 2
So 123435-97-2 is a valid CAS Registry Number.

New straightforward route to an Huperzine A synthetic intermediate

Chassaing, Christophe,Haudrechy, Arnaud,Langlois, Yves

, p. 61 - 68 (1997)

A five step sequence of reactions afforded in high yield the tetrahydroquinoline derivative 3, a key intermediate in Huperzine A synthesis.

Development of a large-scale synthetic route to manufacture (-)-huperzine A

Tudhope, Stephen R.,Bellamy, Julie A.,Ball, Anthony,Rajasekar, Dewakar,Azadi-Ardakani, Manouchehr,Meera, Harihara Subramanian,Gnanadeepam, Jesudoss Mercy,Saiganesh, Ramanathan,Gibson, Frank,He, Linli,Behrens, Carl H.,Underiner, Gail,Marfurt, Judith,Favre, Nathalie

experimental part, p. 635 - 642 (2012/07/28)

A safe, practical and scalable process for manufacture of (-)-huperzine A has been developed and scaled up to manufacture several hundred grams of (-)-huperzine A with chemical and optical purity of >99%. The process consists of 11 chemical stages starting from commercially available materials with only nine isolation steps and no chromatography purification. This process provides a reliable and cost-effective source of synthetic (-)-huperzine A and its derivatives for pharmaceutical and nutraceutical markets.
