Check Digit Verification of cas no
The CAS Registry Mumber 113728-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,7,2 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113728-71:
(8*1)+(7*1)+(6*3)+(5*7)+(4*2)+(3*8)+(2*7)+(1*1)=115
115 % 10 = 5
So 113728-71-5 is a valid CAS Registry Number.

A novel approach to a one-pot synthesis of unsubstituted oligo(α-thiophenes)
Buzhansky, Ludmila,Feit, Ben-Ami
, p. 7523 - 7525 (2007/10/03)
Oligo(α-thiophenes) α-4T and α-8T were prepared by the following one-pot sequential conversions: thiophene (T) → α-2T → α-4T → α-8T. PdCl2-induced coupling of a mono-α-mercuration derivative of each of the n-mers T, α-2T, and α-4T was applied in these conversions.
