Check Digit Verification of cas no

The CAS Registry Mumber 14262-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,6 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14262-61:
(7*1)+(6*4)+(5*2)+(4*6)+(3*2)+(2*6)+(1*1)=84
84 % 10 = 4
So 14262-61-4 is a valid CAS Registry Number.

Preparation of benzo- and polybenzocrown ethers by macrocyclization reactions

Hanes, Robert E.,Lee, Jong Chan,Ivy, Sheryl N.,Palka, Anna,Bartsch, Richard A.

, p. 238 - 248 (2012/11/07)

Macrocyclization of crown ethers and their methods of preparation were explored. We present a robust, scalable method for the preparation of these macrocycles. Additionally, the effect of changing the structures of the precursors was explored to determine whether the 'cut' of bisphenol and dimesylate influenced the course of the reaction as measured by the yield. Further, using catechol derivatives, the method was used for the preparation of monobenzocrown ethers. Interestingly, for the preparation of monobenzocrown ethers, [2+2] adducts were discovered to be significantly contaminating the products. Dimesylates were chosen as the leaving group due to their ease or preparation and the ability to use the unpurified products with no apparent impact on the macrocyclization.
