103142-17-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103142-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,4 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103142-17:
(8*1)+(7*0)+(6*3)+(5*1)+(4*4)+(3*2)+(2*1)+(1*7)=62
62 % 10 = 2
So 103142-17-2 is a valid CAS Registry Number.

The Interconversion of the Lichen Depsides para- and meta-Scrobiculin, and the Biosynthetic Implications
Elix, John A.,Gaul, Kim L.
, p. 613 - 624 (2007/10/02)
An equilibrium mixture of the isomeric depsides para- and meta-scrobiculin has been extracted from the lichen Lobaria scrobiculata.Acetylation of this mixture led to the isolation of two isomeric triacetates, the structures of which were confirmed by anam
