Check Digit Verification of cas no

The CAS Registry Mumber 21315-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,1 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21315-43:
(7*2)+(6*1)+(5*3)+(4*1)+(3*5)+(2*4)+(1*3)=65
65 % 10 = 5
So 21315-43-5 is a valid CAS Registry Number.

PdI2-catalyzed regioselective cyclocarbonylation of 2-allyl phenols to dihydrocoumarins

Amzquita-Valencia, Manuel,Alper, Howard

, p. 5827 - 5829 (2014)

A simple, efficient, and regioselective synthesis of 3-methyl-3,4-dihydrocoumarins is reported. The reaction of 2-allyl phenols with synthesis gas was catalyzed by PdI2, and 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane (L1) and 1,3,5,7-tetramethyl-6-tetradecyl-2,4,8-trioxa-6-phosphaadamantane (L2) were effective as ligands, affording good product selectivity in all cases.
