Check Digit Verification of cas no

The CAS Registry Mumber 1239913-53-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,1 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1239913-53:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*1)+(3*3)+(2*5)+(1*3)=171
171 % 10 = 1
So 1239913-53-1 is a valid CAS Registry Number.

Synthesis of dibenzothiophenes and related classes of heterocycles by using functionalized dithiocarbamates

Kienle, Marcel,Unsinn, Andreas,Knochel, Paul

supporting information; experimental part, p. 4751 - 4754 (2010/09/15)

Chemical Equation Presentation A round trip: Readily available dithiocarbamates can undergo ring closure to give functionalized sulfur heterocycles (see scheme). These heteroaromatic compounds can be further functionalized by directed alumination and subsequently trapped with various electrophiles.
