238739-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 238739-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,7,3 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 238739-95:
(8*2)+(7*3)+(6*8)+(5*7)+(4*3)+(3*9)+(2*9)+(1*5)=182
182 % 10 = 2
So 238739-95-2 is a valid CAS Registry Number.

Radical reactions leading to substituted coumarins
Giraud, Anne,Vanelle, Patrice,Giraud, Luc
, p. 4321 - 4322 (2007/10/03)
The reaction of 4-hydroxycoumarins with a series of quinonic chlorides under photostimulation was shown to provide an efficient approach to 3- alkylated coumarin derivatives. Alkylation reactions of this type proceeded via an electron transfer mechanism (
