Check Digit Verification of cas no

The CAS Registry Mumber 121153-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,5 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121153-32:
(8*1)+(7*2)+(6*1)+(5*1)+(4*5)+(3*3)+(2*3)+(1*2)=70
70 % 10 = 0
So 121153-32-0 is a valid CAS Registry Number.

Na-Y zeolite, an efficient catalyst for the methoxymethylation of alcohols

Kumari, Pradeep,Raju, Satya V.N.,Reddy, Ravinder S.,Pandey, Bipin

, p. 1289 - 1290 (1994)

A variety of hydroxy compounds react with methoxymethyl chloride in the presence of catalytic amount of Na-Y zeolite to afford the corresponding methoxymethyl ethers (MOM ethers) in excellent yields.

An efficient protocol for the preparation of MOM ethers and their deprotection using zirconium(IV) chloride

Sharma,Reddy, K. Laxma,Sree Lakshmi,Radha Krishna, Palakodety

, p. 9229 - 9232 (2007/10/03)

An efficient protocol for the preparation of MOM ethers from alcohols and formaldehyde dimethyl acetal (DMFA) using ZrCl4 (10 mol %) at room temperature under solvent free conditions has been developed. Similarly, the same Lewis acid, ZrCl4 (50 mol %), in isopropanol at reflux was utilised for the deprotection of MOM ethers.
