Check Digit Verification of cas no

The CAS Registry Mumber 201416-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,4,1 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201416-09:
(8*2)+(7*0)+(6*1)+(5*4)+(4*1)+(3*6)+(2*0)+(1*9)=73
73 % 10 = 3
So 201416-09-3 is a valid CAS Registry Number.

Ni-catalyzed reduction of inert C-O bonds: A new strategy for using aryl ethers as easily removable directing groups

Alvarez-Bercedo, Paula,Martin, Ruben

, p. 17352 - 17353 (2011/02/23)

An efficient Ni-catalyzed protocol for the reductive cleavage of inert C-O bonds has been developed. The method is characterized by its simplicity and wide scope, thereby allowing the use of aryl ethers as easily removable directing groups in organic synthesis.
