Check Digit Verification of cas no

The CAS Registry Mumber 67139-60-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,3 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67139-60:
(7*6)+(6*7)+(5*1)+(4*3)+(3*9)+(2*6)+(1*0)=140
140 % 10 = 0
So 67139-60-0 is a valid CAS Registry Number.

A Copper-Catalyzed Formal [3 + 2]-Cycloaddition for the Synthesis of All Different Aryl-Substituted Furans and Thiophenes

Ishikawa, Shingo,Noda, Yushi,Wada, Masaru,Nishikata, Takashi

, p. 7555 - 7563 (2015)

A highly efficient formal [3 + 2]-cycloaddition was established using a copper catalyst. The resulting dihydrofurans were subjected to oxidation followed by arylations to produce tetraarylfurans. In addition, the dihydrofuran can be converted to diaryldih
