92125-68-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92125-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,2 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92125-68:
(7*9)+(6*2)+(5*1)+(4*2)+(3*5)+(2*6)+(1*8)=123
123 % 10 = 3
So 92125-68-3 is a valid CAS Registry Number.

On the origin of siphonariid polypropionates: Total synthesis of caloundrin B and its isomerization to siphonarin B

Becerril-Jimenez, Fabiola,Ward, Dale E.

, p. 1648 - 1651 (2012)

Enantioselective synthesis of the enantiomer of caloundrin B was achieved by strategic aldol coupling of an enantiopure trioxaadamantane-containing ketone with a racemic pyrone-containing aldehyde via kinetic resolution. In the presence of imidazole, ent-
