Check Digit Verification of cas no

The CAS Registry Mumber 26177-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,7 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26177-25:
(7*2)+(6*6)+(5*1)+(4*7)+(3*7)+(2*2)+(1*5)=113
113 % 10 = 3
So 26177-25-3 is a valid CAS Registry Number.

Synthesis and Properties of Dinitromethylated Arenes. Reinvestigation of the Ponzio Reaction

Suzuku, Hitomi,Takaoka, Hiroshi,Yamamoto, Hidetoshi,Ogawa, Takuji

, p. 2927 - 2932 (1988)

Several title compounds have been prepared by the modified Ponzio procedure and their IR, 1 H and 13 C NMR data are presented.In some cases trinitromethylated arenes were obtained as a by-product.Oxidative cleavage to parent aldehydes and oxidation to carboxylic acids were the major competing reactions. 9-Anthracenecarbaldehyde oxime and 10-methyl-9-anthracenecarbaldehyde oxime reacted with nitrogen dioxide in an unexpected way, giving 10-nitro-9-anthracenecarbonitrile oxide and 10-methyl-10-nitro-9-anthrone as the respective main products.Nitration of (dinitromethyl)benzene has also been examined under various conditions.
