Check Digit Verification of cas no

The CAS Registry Mumber 31271-10-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,7 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31271-10:
(7*3)+(6*1)+(5*2)+(4*7)+(3*1)+(2*1)+(1*0)=70
70 % 10 = 0
So 31271-10-0 is a valid CAS Registry Number.

Chemistry of α-mangostin. Studies on the semisynthesis of minor xanthones from Garcinia mangostana

Morelli, Carlo F.,Biagiotti, Marco,Pappalardo, Valeria M.,Rabuffetti, Marco,Speranza, Giovanna

, p. 750 - 755 (2015)

α-Mangostin is the major prenylated xanthone from Garcinia mangostana and it has been used also in recent times as starting material for the semisynthetic preparation of various biologically active derivatives. Its structure is characterised by the presence of few functional groups amenable to chemical manipulations, but present in the molecule in multiple instances (three phenolic hydroxyl groups, two prenyl chains and two unsubstituted aromatic carbons). This study represents a first approach to the systematic investigation of the reactivity of α-mangostin and describes the semisynthesis of some minor xanthones isolated from G. mangostana.
