Check Digit Verification of cas no

The CAS Registry Mumber 465498-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,5,4,9 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 465498-64:
(8*4)+(7*6)+(6*5)+(5*4)+(4*9)+(3*8)+(2*6)+(1*4)=200
200 % 10 = 0
So 465498-64-0 is a valid CAS Registry Number.

A facile synthesis of 4-diarylmethyl-1-(2H)phthalazinones from 2,2-diaryl-1,3-indanediones

Kundu, Sandip Kumar,Pramanik, Animesh,Patra, Amarendra

, p. 823 - 825 (2002)

Refluxing of 2,2-diaryl-1,3-indanediones in hydrazine hydrate for a brief period affords 4-diarylmethyl-1-(2H)phthalazinones in very high yield.

Facile synthesis of 3-(diarylmethylene)isobenzofuranones, 4-(diarylmethyl)-1(2H)-phthalazinones and diarylmethanes

Das, Suven,Froehlich, Roland,Pramanik, Animesh

, p. 84 - 86 (2007/10/03)

Reflux of 2,2-diaryl-1,3-indanediones in ethyleneglycol with a catalytic amount of triethylamine affords 3-(diarylmethylene)isobenzofuranones in very good yields. The latter produces 4-diarymethyl-1(2H)-phthalazinones under reflux in hydrazine hydrate (99%), and diarylmethanes upon stirring in ethylenediamine.

A convenient synthesis of 4-diarylmethyl-, 4-(α-hydroxy- α-aryl/naphthyl)methyl- and 4-(benzoyl/naphthanoyl)-1-(2H)-phthalazinones from ninhydrin

Kundu, Sandip Kumar,Pramanik, Animesh

, p. 595 - 603 (2007/10/03)

Refluxing of 2,2-diaryl-1,3-indanediones in hydrazine hydrate for a brief period affords 4-diarylmethyl-1-(2H) phthalazinones in very high yield. A series of 4-(α-hydroxy-α-aryl/naphthyl)methyl- and 4-(benzoyl/naphthanoyl)-1-(2H) phthalazinones also have
