Check Digit Verification of cas no

The CAS Registry Mumber 916659-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,6,5 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 916659-24:
(8*9)+(7*1)+(6*6)+(5*6)+(4*5)+(3*9)+(2*2)+(1*4)=200
200 % 10 = 0
So 916659-24-0 is a valid CAS Registry Number.

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

Das, Suven,Froehlich, Roland,Pramanik, Animesh

, p. 84 - 86 (2006)

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.
