Check Digit Verification of cas no

The CAS Registry Mumber 1297409-65-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,4,0 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1297409-65:
(9*1)+(8*2)+(7*9)+(6*7)+(5*4)+(4*0)+(3*9)+(2*6)+(1*5)=194
194 % 10 = 4
So 1297409-65-4 is a valid CAS Registry Number.

Base-catalyzed cascade 1,3-H shift/cyclization reaction to construct polyaromatic furans

Wang, Ya-Hui,Liu, Heng,Zhu, Li-Li,Li, Xiao-Xiao,Chen, Zili

, p. 707 - 712 (2011)

A convenient new method was developed to prepare unfused polyaromatic furan derivatives from diynyl-1,6-diols through a novel base-catalyzed cascade 1,3-H shift/cyclization process. Deuterium experiments were performed to determine that the 1,3-H shift was the rate-determining step. Copyright
