Check Digit Verification of cas no

The CAS Registry Mumber 13031-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,3 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13031-01:
(7*1)+(6*3)+(5*0)+(4*3)+(3*1)+(2*0)+(1*1)=41
41 % 10 = 1
So 13031-01-1 is a valid CAS Registry Number.

Study on the Transannular Lead Tetraacetate Oxidation of Some Medium-sized Ring Diketone Bis(arylhydrazones)

Malamidou-Xenikaki, Elizabeth,Alexandrou, Nicholas E.

, p. 280 - 286 (2007/10/02)

Oxidation of bis(arylhydrazones) 1a-d of 1,5-cyclooctanedione with lead tetraacetate mainly leads, via a transannular reaction, to the corresponding bicyclic bis(arylazo) compounds 3a-d, whereas bis(arylhydrazones) 2a-d of 3,8-cyclodecadiene-1,6-dione under the same conditions mainly give monocyclic bis(acetoxy)bis(arylazo) products 6a-d.The reaction of bis(arylazo) derivatives 3 with sulfuric acid is also examined.
