91766-35-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91766-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,6 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91766-35:
(7*9)+(6*1)+(5*7)+(4*6)+(3*6)+(2*3)+(1*5)=157
157 % 10 = 7
So 91766-35-7 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 (
