Check Digit Verification of cas no

The CAS Registry Mumber 918419-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,4,1 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 918419-01:
(8*9)+(7*1)+(6*8)+(5*4)+(4*1)+(3*9)+(2*0)+(1*1)=179
179 % 10 = 9
So 918419-01-9 is a valid CAS Registry Number.

Method for Production of Substituted Phenylmalonate Esters, Novel Phenylmalonate Esters and Use Thereof

-

Page/Page column 4, (2008/12/08)

A process for preparing substituted phenylmalonic esters of the formula in which R is alkyl and Q is halogen, alkyl, alkoxy, haloalkyl or haloalkoxy and the index m is an integer from 1 to 5, where the groups Q can be identical or different if the index m is greater than 1, comprising steps A), B) and C): A) reaction of compounds of the formula II, in which the variables are as defined for formula I to give compounds of the formula III, B) conversion of the compounds of the formula III into ketals of the formula IV in which R′ is C1-C4-alkyl or benzyl, C) hydrolysis of the compounds of the formula IV to give compounds of the formula I; novel phenylmalonic ester derivatives, and their use as intermediates.
