Check Digit Verification of cas no

The CAS Registry Mumber 602313-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,2,3,1 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 602313-45:
(8*6)+(7*0)+(6*2)+(5*3)+(4*1)+(3*3)+(2*4)+(1*5)=101
101 % 10 = 1
So 602313-45-1 is a valid CAS Registry Number.

A facile two-step synthesis of 2-arylbenzofurans based on the selective cross McMurry couplings

Duan, Xin-Fang,Zeng, Jing,Zhang, Zhan-Bin,Zi, Guo-Fu

, p. 10283 - 10286 (2008/04/05)

(Chemical Equation Presented) A novel two-step synthesis of 2-arylbenzofurans has been developed. It involves a selective cross McMurry coupling of a salicylaldehyde or substituted salicylaldehyde with an aromatic aldehyde and a sequential oxidative cyclization of the resulting ortho-vinylphenols. Utilizing this synthetic protocol, a variety of 2-arylbenzofurans including cicerfuran (5) have been efficiently synthesized.
