Check Digit Verification of cas no

The CAS Registry Mumber 1301225-26-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,2,2 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1301225-26:
(9*1)+(8*3)+(7*0)+(6*1)+(5*2)+(4*2)+(3*5)+(2*2)+(1*6)=82
82 % 10 = 2
So 1301225-26-2 is a valid CAS Registry Number.

Transition-metal-free intramolecular Ullmann-type O-arylation: Synthesis of chromone derivatives

Zhao, Jie,Zhao, Yufen,Fu, Hua

supporting information; experimental part, p. 3769 - 3773 (2011/05/15)

(Chemical Equation Presented) Expect the upexpected: A transition-metal- free approach to access chromone derivatives has been developed. The intramolecular O-arylation of substituted 1-(2-haloaryl)-propane-1,3-diones in DMF in the presence of K2CO3 gave the corresponding target products in good to excellent yields (see scheme; DMF = N,N′- dimethylformamide).
