477772-17-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 477772-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,7,7 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 477772-17:
(8*4)+(7*7)+(6*7)+(5*7)+(4*7)+(3*2)+(2*1)+(1*7)=201
201 % 10 = 1
So 477772-17-1 is a valid CAS Registry Number.

An enantioselective synthetic pathway towards plakortones
Lee, Hing Ken,Wong, Henry N. C.
, p. 2114 - 2115 (2007/10/03)
An enantioselective synthesis of functionalized bicyclic lactones 2, 3 and 4, core structures of plakortones, are described; the configurations of 2,3 and 4 were confirmed by X-ray crystallographic analyses of their precursors 11, 19 and 24, respectively.
