Check Digit Verification of cas no

The CAS Registry Mumber 1402544-42-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,5,4 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1402544-42:
(9*1)+(8*4)+(7*0)+(6*2)+(5*5)+(4*4)+(3*4)+(2*4)+(1*2)=116
116 % 10 = 6
So 1402544-42-6 is a valid CAS Registry Number.

A mild and versatile method for the synthesis of alkyl ethers from methoxymethyl ethers and application to the preparation of sterically crowded ethers

supporting information; scheme or table, p. 1861 - 1866 (2012/09/22)

A mild and divergent route for the synthesis of alkyl ethers from methoxymethyl (MOM) and methoxyethyl (ME) ether derivatives via pyridinium-type salt intermediates has been developed. The addition of organocuprates to the salts afforded the corresponding alkyl ethers, including highly crowded ones, in high yields even in the presence of acid- or base-sensitive functional groups.
