130293-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130293-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,9 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130293-26:
(8*1)+(7*3)+(6*0)+(5*2)+(4*9)+(3*3)+(2*2)+(1*6)=94
94 % 10 = 4
So 130293-26-4 is a valid CAS Registry Number.

Tetraphenylporphine-sensitized photooxygenation of benzofuran derivatives 1 afforded the corresponding benzofuran dioxetanes 2 in good yields.Allylic hydroperoxides 3 were formed regioselectively from 2,3-dimethyl-substituted benzofurans as minor products
