Check Digit Verification of cas no

The CAS Registry Mumber 58710-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,7,1 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 58710-61:
(7*5)+(6*8)+(5*7)+(4*1)+(3*0)+(2*6)+(1*1)=135
135 % 10 = 5
So 58710-61-5 is a valid CAS Registry Number.

Carbonylation of aryl chlorides with oxygen nucleophiles at atmospheric pressure. Preparation of phenyl esters as acyl transfer agents and the direct preparation of alkyl esters and carboxylic acids

Watson, Donald A.,Fan, Xuexiang,Buchwald, Stephen L.

supporting information; experimental part, p. 7096 - 7101 (2009/05/09)

(Chemical Equation Presented) A mild, functional group tolerant method of the preparation of phenyl esters from aryl chlorides via palladium-catalyzed carbonylation is described using atmospheric pressure of carbon monoxide. Phenyl esters are shown to be useful acylating agents, delivering libraries of carbonyl derivatives, including alkyl, allyl and thioesters, under very mild conditions. Direct preparation of alkyl esters and carboxylic acids is also demonstrated, providing the first method for the preparation of methyl and ethyl esters from aryl chlorides without pressured reactors.
