328047-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 328047-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,0,4 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 328047-30:
(8*3)+(7*2)+(6*8)+(5*0)+(4*4)+(3*7)+(2*3)+(1*0)=129
129 % 10 = 9
So 328047-30-9 is a valid CAS Registry Number.

A mercury-catalyzed transetherification cyclization leading to fused cyclic polyethers
Tan,Schreiber
, p. 9509 - 9513 (2007/10/03)
Dihydropyran 6 serves as a key intermediate in a route to fused cyclic polyethers. The dihydropyran was first converted to 2-hydroxy-1-γ-methoxyallyltetrahydropyrans, 10. Mercury trifluoroacetate-catalyzed transetherification cyclization generated new bic
