Check Digit Verification of cas no

The CAS Registry Mumber 14593-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14593-45:
(7*1)+(6*4)+(5*5)+(4*9)+(3*3)+(2*4)+(1*5)=114
114 % 10 = 4
So 14593-45-4 is a valid CAS Registry Number.

Clay catalyzed highly selective O-alkylation of primary alcohols with orthoesters

Kumar, H. M. Sampath,Reddy, B. V. Subba,Mohanty, Pradyumna K.,Yadav

, p. 3619 - 3622 (1997)

Montmorillonite KSF catalyzes the selective O-alkylation of various primary allylic and benzylic alcohols when reacted with different orthoesters at room temperature to afford ethers in moderate to high yields.

Reaction of orthoesters with alcohols in the presence of acidic catalysts: A study

Sampath Kumar,Joyasawal, Sipak,Reddy,Pawan Chakravarthy,Krishna,Yadav

, p. 1686 - 1692 (2007/10/03)

Allylic and benzylic alcohols are converted into corresponding unsymmetrical ethers when reacted with various orthoesters in the presence of montmorillonite KSF at ambient temperature. A detailed study has been undertaken to examine the mechanism and generality of these reactions with regard to various acidic catalysts, which reveal interesting competitive reactions mainly O-acetylation, together with trace amount of dimerized product. The type of the side product and their relative quantity depends upon the nature of the catalyst employed. Furthermore, the low yields of the Claisen rearrangement product obtained from allylic alcohols under heating is rationalized due to the formation of some of these products.
