Check Digit Verification of cas no

The CAS Registry Mumber 15420-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,4,2 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15420-17:
(7*1)+(6*5)+(5*4)+(4*2)+(3*0)+(2*1)+(1*7)=74
74 % 10 = 4
So 15420-17-4 is a valid CAS Registry Number.

One-pot ester synthesis from allyl and benzyl halides and alcohols by palladium-catalyzed carbonylation

Tommasi, Sara,Perrone, Serena,Rosato, Francesca,Salomone, Antonio,Troisi, Luiginio

experimental part, p. 423 - 430 (2012/03/11)

A mild and efficient one-pot synthesis of esters based on the Pd-catalyzed alkoxy- and aryloxycarbonylation of allylic and benzylic halides is described. The methodology has been applied to primary, secondary, and tertiary alcohols as well as to phenol derivatives. The O-protection of some biologically relevant molecules is also reported.
