Check Digit Verification of cas no

The CAS Registry Mumber 118818-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,1 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118818-35:
(8*1)+(7*1)+(6*8)+(5*8)+(4*1)+(3*8)+(2*3)+(1*5)=142
142 % 10 = 2
So 118818-35-2 is a valid CAS Registry Number.

A Convenient Synthesis of 5-Aryltropolones via Novel Benzidine Type Rearrangement of 2-(2-Arylhydrazino)tropones

Nozoe, Tetsuo,Takase, Kahei,Saito, Hiroaki,Yamamoto, Hiroshi,Imafuku, Kimiaki

, p. 1577 - 1580 (2007/10/02)

Treatment of a wide variety of 2-(2-arylhydrazino)tropones with ethanolic acid at 50-80 deg C readily gave the benzidine type rearrangement products, i.e. 2-amino-5-(4-aminoaryl)tropones, which in turn were conveniently led to the corresponding 5-aryltropolones that can be utilized for synthesizing B-ring-open analogues of colchicine.
