Check Digit Verification of cas no
The CAS Registry Mumber 7312-24-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,1 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7312-24:
(6*7)+(5*3)+(4*1)+(3*2)+(2*2)+(1*4)=75
75 % 10 = 5
So 7312-24-5 is a valid CAS Registry Number.

scheme or table, p. 3736 - 3739 (2011/08/06)
A practical route to prepare halogeno-derivatives is described, starting from easily available 3-cyano-benzo[b]thiophene. Main efforts have been devoted to the optimization of the experimental procedures (solvent, bromination) to promote selectivity. Synt
