Check Digit Verification of cas no
The CAS Registry Mumber 31777-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,7 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31777-46:
(7*3)+(6*1)+(5*7)+(4*7)+(3*7)+(2*4)+(1*6)=125
125 % 10 = 5
So 31777-46-5 is a valid CAS Registry Number.

The Oxidative-Rearrangement of Nitrogen Heterocycles with Lead Tetraacetate and t-Buty Hypochlorite
Zey, Robert L.
, p. 847 - 849 (2007/10/02)
Mechanisms for the lead tetraacetate and t-butyl hypochlorite oxidation of 1,4-dihydro-3(2H)-cinnolinones and 1-amino-2-indolinones are discussed.Evidence for the lack of a nitrene intermediate is given.
