Check Digit Verification of cas no

The CAS Registry Mumber 1132988-93-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,9,8 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1132988-93:
(9*1)+(8*1)+(7*3)+(6*2)+(5*9)+(4*8)+(3*8)+(2*9)+(1*3)=172
172 % 10 = 2
So 1132988-93-2 is a valid CAS Registry Number.

Total synthesis and metabolic stability of hispidulin and its d-labelled derivative

Chen, Liang-Chieh,Hsu, Kai-Cheng,Chiou, Lih-Chu,Tseng, Hui-Ju,Huang, Wei-Jan

, (2017)

Hispidulin is a naturally occurring flavone known to have various Central nervous system (CNS) activities. Proposed synthetic approaches to synthesizing hispidulin have proven unsatisfactory due to their low feasibility and poor overall yields. To solve these problems, this study developed a novel scheme for synthesizing hispidulin, which had an improved overall yield as well as more concise reaction steps compared to previous methods reported. Additionally, using the same synthetic strategy, d-labelled hispidulin was synthesized to investigate its metabolic stability against human liver microsome. This work may produce new chemical entities for enriching the library of hispidulin-derived compounds.

Tandem Chloropalladation/Cyclization and Dearomative Cyclization toward Functionalized Tricyclic Bridged [3.2.1] Skeleton Compounds

Dong, Yi,Du, Nana,Li, Xueyuan,Zheng, Litao,Liu, Gang

, p. 4110 - 4113 (2015/09/01)

A palladium-catalyzed tandem reaction is reported that involves chloropalladation/cyclization and dearomative cyclization to construct a tricyclic bridged [3.2.1] carbocyclic-skeleton and oxa- and aza-skeletons. In this domino process, a level of ring strain and other competitive reactions, i.e., protonolysis, β-hydride elimination, and chlorination of the C-Pd bond, were suppressed to the lowest level under mild reaction conditions.
