Check Digit Verification of cas no

The CAS Registry Mumber 391687-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,6,8 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 391687-99:
(8*3)+(7*9)+(6*1)+(5*6)+(4*8)+(3*7)+(2*9)+(1*9)=203
203 % 10 = 3
So 391687-99-3 is a valid CAS Registry Number.

The preparation of chiral salicylaldehydes based on Kagan's ether

Harmata,Wu,Kahraman,Welch

, p. 3345 - 3359 (2007/10/03)

Two related routes to chiral salicylaldehydes which are derivatives of Kagan's ether have been developed. One route which is particularly simple begins with 2,6-diallylphenol. Facile conversion to a substituted benzofuran and assemblage of the basic framework of Kagan's ether is followed by an ozonolysis of the benzofuran ring to reveal the hydroxyaldehyde functionality characteristic of salicylaldehydes.
