Check Digit Verification of cas no

The CAS Registry Mumber 109423-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109423-19:
(8*1)+(7*0)+(6*9)+(5*4)+(4*2)+(3*3)+(2*1)+(1*9)=110
110 % 10 = 0
So 109423-19-0 is a valid CAS Registry Number.

Revisitation of the Reaction between Aniline and Formaldehyde. VI. The Accumulated Amide Ester Function from Addition of Carboxylic Anhydrides to N-Methyleneamines or Their Trimers

Giumanini, Angelo G.,Verardo, Giancarlo,Cauci, Sabina

, p. 417 - 432 (2007/10/02)

Some aliphatic carboxylic anhydrides gave excellent yields of the novel addition products to both aliphatic and aromatic N-methyleneimines, starting from their aliphatic and aromatic trimeric cyclic oligomers.A preliminary positive ion mass spectrometric study is here reported.They hydrolyze surprisingly faster than the corresponding acid amides, making necessary the intervention of a special mechanism.The reduction of the acetylamideester of cyclohexylmethyleneimine (3c) with LiAlH4 was also "abnormal", as it yielded N-methyl-N-ethylcyclohexylamine in quantitative yield.
