Check Digit Verification of cas no
The CAS Registry Mumber 91099-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,9 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91099-01:
(7*9)+(6*1)+(5*0)+(4*9)+(3*9)+(2*0)+(1*1)=133
133 % 10 = 3
So 91099-01-3 is a valid CAS Registry Number.

Synthetic Approaches to Phthalazines: C-N Bond Cleavage in 2'-Benzylbenzohydrazides During Reaction with Polyphosphoric Acid
Paul, D. Brenton
, p. 893 - 901 (2007/10/02)
Reaction of 2'-benzylbenzohydrazides with concentrated polyphosphoric acid gave 2,5-diaryl-1,3,4-oxadiazoles and a polybenzyl.Cyclodehydration to phthalazines was not observed.It is inferred from product substitution patterns that CH2-N bond cleavage occurs with polybenzyls forming from the benzyl moiety and oxadiazoles from the benzohydrazide fragment.Other reported reactions which generate benzyl fragments lead to bibenzyl and are considered to involve trapping of the cleavage products within a solvent cage.The observed production of polybenzyls is therefore interpreted in terms of the formation of free benzyl fragments.A tetrahydrophthalazine derivative was produced from the addition of diethyl azodicarboxylate to the photodiene of o-methylbenzophenone, but this could not be converted into a phthalazine.
