119680-72-7 Usage
Derived from D-gulono-lactone
It is derived from D-gulono-lactone, which is a precursor to L-ascorbic acid (Vitamin C).
Dicyclohexylidene group
The dicyclohexylidene group is often used to protect the aldehyde or ketone functional groups in organic synthesis.
Cyclic structure
It has a cyclic structure with two cyclohexane rings connected to the D-gulono-lactone framework.
Check Digit Verification of cas no
The CAS Registry Mumber 119680-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,6,8 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119680-72:
(8*1)+(7*1)+(6*9)+(5*6)+(4*8)+(3*0)+(2*7)+(1*2)=147
147 % 10 = 7
So 119680-72-7 is a valid CAS Registry Number.

Enantiospecific Syntheses of Aristeromycin and Neplanocin A
Wolfe, Michael S.,Anderson, Blake L.,Borcherding, David R.,Borchardt, Ronald T.
, p. 4712 - 4717 (1990)
The carbocylic nucleosides (-)-aristeromycin and (-)-neplanocin A were made enantiospecifically in nine steps and ten steps, respectively, from D-ribonic acid γ-lactone.Quenching of an organocuprate conjugate addition reaction with either acetic acid or methanesulfinyl chloride determines whether the divergent synthetic route branches toward (-)-aristeromycin or (-)-neplanocin A.An alternate synthesis of cyclopentenone 1, a common intermediate to these compounds, from D-gulonic acid γ-lactone is also described.
