928259-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928259-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,2,5 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 928259-87:
(8*9)+(7*2)+(6*8)+(5*2)+(4*5)+(3*9)+(2*8)+(1*7)=214
214 % 10 = 4
So 928259-87-4 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of ethyl (1R,2S)-dehydrocoronamate
Fox, Martin E.,Lennon, Ian C.,Farina, Vittorio
, p. 945 - 948 (2007)
A synthesis of (1R,2S)-dehydrocoronamic acid ethyl ester was developed employing a regio- and enantioselective palladium-catalysed nucleophilic ring-opening of 3,4-epoxy-1-butene with a glycine anion equivalent as the key enantiodifferentiating step. The
