Check Digit Verification of cas no

The CAS Registry Mumber 502844-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,8,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 502844-71:
(8*5)+(7*0)+(6*2)+(5*8)+(4*4)+(3*4)+(2*7)+(1*1)=135
135 % 10 = 5
So 502844-71-5 is a valid CAS Registry Number.

A route to 5-substituted dibenzofurans by anionic cycloaromatization of 2-(6-substituted 3-hexen-1,5-diynyl)phenyl tert-butyldimethyl ethers and related molecules

Wu, Ming-Jung,Lee, Chia-Ying,Lin, Chi-Fong

, p. 4077 - 4079 (2007/10/03)

An anionic cycloaromatization reaction provides an efficient method for the synthesis of the dibenzofurans 2 by treatment of the tert-butyldimethylsilyl ethers 1 with sodium methoxide or potassium carbonate in methanol at reflux for 16 h, and gives 50-94%
