Check Digit Verification of cas no

The CAS Registry Mumber 123053-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,5 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123053-76:
(8*1)+(7*2)+(6*3)+(5*0)+(4*5)+(3*3)+(2*7)+(1*6)=89
89 % 10 = 9
So 123053-76-9 is a valid CAS Registry Number.

Regioselective Alkoxycarbonylation of Allyl Phenyl Ethers Catalyzed by Pd/dppb under Syngas Conditions

Amézquita-Valencia, Manuel,Alper, Howard

, p. 3860 - 3867 (2016/05/24)

A simple and regioselective synthesis of phenoxy esters and phenylthio esters is reported. The products are obtained by selective alkoxycarbonylation catalyzed by Pd2(dba)3, 1,4-bis(diphenylphisphino)butane (dppb), and syngas (CO/H2) in chloroform/alcohol. This methodology affords bifunctional products in good yield with excellent n-selectivity and without the need to use additives.
