Check Digit Verification of cas no

The CAS Registry Mumber 26232-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,2,3 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26232-97:
(7*2)+(6*6)+(5*2)+(4*3)+(3*2)+(2*9)+(1*7)=103
103 % 10 = 3
So 26232-97-3 is a valid CAS Registry Number.

Transition-Metal-Free Valorization of Biomass-derived Levulinic Acid Derivatives: Synthesis of Curcumene and Xanthorrhizol

Fu, Yao,Gong, Tian-Jun,Xu, Wen-Yan,Zhuo, Kai-Feng

, p. 884 - 891 (2020/12/13)

Levulinic acid (LA) is acknowledged one of the most promising biomass-derived platform molecules and can be transformed into various value-added chemicals. Here, we report a new reaction process for the valorization of LA derivatives under transition-meta

Heteroatom-directed Wacker oxidations. A protection-free synthesis of (-)-heliophenanthrone

Mukherjee, Parag,Sarkar, Tarun K.

supporting information; experimental part, p. 3060 - 3065 (2012/05/07)

The first enantioselective six-step synthesis of (-)-heliophenanthrone has been achieved without any protection-deprotection protocol at an overall yield of 28%. Key features of this synthesis comprise a heteroatom-directed Wacker oxidation of an internal cyclic olefin in addition to asymmetric Brown allylation and ring closing metathesis (RCM).

Direct synthesis of (+)-erogorgiaene through a kinetic enantiodifferentiating step

Davies, Huw M. L.,Walji, Abbas M.

, p. 1733 - 1735 (2007/10/03)

(Chemical Equation Presented) The combined approach of C-H activation and a Cope rearrangement catalyzed by a rhodium catalyst [Rh2(R-dosp) 4] (dosp = (N-dodecylbenzenesulfonyl)prolinate) is shown to be a very effective method for the construction of the three stereogenic centers (marked in red, see scheme) present in the diterpene erogorgiaene (1).
