869953-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 869953-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,9,5 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 869953-72:
(8*8)+(7*6)+(6*9)+(5*9)+(4*5)+(3*3)+(2*7)+(1*2)=250
250 % 10 = 0
So 869953-72-0 is a valid CAS Registry Number.

Synthesis of the floresolide B hydroquinone lactone core using ring-closing metathesis
Briggs, Timothy F.,Dudley, Gregory B.
, p. 7793 - 7796 (2007/10/03)
The hydroquinone lactone core of the floresolides was synthesized through a ring-closing metathesis (RCM) approach. Optimal RCM efficiency was obtained at higher reaction concentration. An unexpected Lewis acid-promoted rearrangement of the hydroquinone a
