300807-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 300807-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,8,0 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 300807-58:
(8*3)+(7*0)+(6*0)+(5*8)+(4*0)+(3*7)+(2*5)+(1*8)=103
103 % 10 = 3
So 300807-58-3 is a valid CAS Registry Number.

A general oxidative cyclization of 1,5-dienes using catalytic osmium tetroxide
Donohoe, Timothy J.,Butterworth, Sam
, p. 948 - 951 (2003)
Dihydroxylation of 1,5-dienes under acidic conditions is sufficient to induce an efficient oxidative cyclization that produces stereochemically defined tetrahydrofurans in one step [Eq. (1)]. This method is very general and efficient for a range of dienes
