Check Digit Verification of cas no

The CAS Registry Mumber 1727-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,2 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1727-39:
(6*1)+(5*7)+(4*2)+(3*7)+(2*3)+(1*9)=85
85 % 10 = 5
So 1727-39-5 is a valid CAS Registry Number.

Visible-light promoted oxidative cyclization of cinnamic acid derivatives using xanthone as the photocatalyst

Zhao, Bin,Xu, Bo

supporting information, p. 568 - 573 (2021/02/06)

We have developed an efficient photocatalytic synthesis of coumarin derivativesviaa tandem double bond isomerization/oxidative cyclization of cinnamic acids. Inexpensive and stable xanthone was used as the photocatalyst, and readily available Selectfluor was used as the oxidant. This method tolerates a wide range of functional groups and offers excellent chemical yields in general. Besides, the photocatalytic oxidative cyclization of cinnamic acid esters gives dimerized lignan-type products.
