146713-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146713-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,7,1 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 146713-95:
(8*1)+(7*4)+(6*6)+(5*7)+(4*1)+(3*3)+(2*9)+(1*5)=143
143 % 10 = 3
So 146713-95-3 is a valid CAS Registry Number.

Concise Synthetic Approaches to Naturally Occurring β- Hydroxypyranochalcones: First Total Synthesis of Purpurenone, Its Derivative, and Praecansone B
Wang, Xue,Lee, Yong Rok,Kim, Sung Hong
, p. 2647 - 2650 (2012/10/29)
The total synthesis of biologically interesting β- hydroxypyranochalcones, purpurenone (1), its derivative 2, praecansone B (3), and pongapinone A (4) has been accomplished starting from commercially available 2,4-dihydroxyacetophenone or 6-methoxy-2,4-di
