Check Digit Verification of cas no

The CAS Registry Mumber 59223-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,2 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 59223-78:
(7*5)+(6*9)+(5*2)+(4*2)+(3*3)+(2*7)+(1*8)=138
138 % 10 = 8
So 59223-78-8 is a valid CAS Registry Number.

Solvent-Controlled Hydrogenation of 2’-Hydroxychalcones: A Simple Solution to the Total Synthesis of Bussealins

Soto, Martín,Soengas, Raquel G.,Rodríguez-Solla, Humberto

, p. 5422 - 5431 (2020/10/06)

A solvent-controlled hydrogenation of 2’-hydroxychalcones to selectively obtain different hydrogenation products is herein reported. Thus, hydrogenation of 2’-hydroxychalcones using EtOH as solvent provided the corresponding 1,3-diarylpropanes in excellent yields. On the contrary, when the hydrogenation was performed in DCM, the corresponding dihydrochalcones were isolated. Switching the reaction solvent to n-BuOH/H2O (1:1), afforded 1,3-diarylpropanols from moderate to good yields. The methodology here reported offers a straightforward, simple and cost-effective method for the preparation of a wide variety of 2’-hydroxy-1,3-diarylpropanes derivatives, and was also applied to the preparation of natural Bussealins C and D. (Figure presented.).
