Check Digit Verification of cas no

The CAS Registry Mumber 2017-93-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,1 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2017-93:
(6*2)+(5*0)+(4*1)+(3*7)+(2*9)+(1*3)=58
58 % 10 = 8
So 2017-93-8 is a valid CAS Registry Number.

Acid Acides: Part IX - Synthesis and Reactions of Phthalimidoacetic Acid Azide and Its Derivatives

Aly, N. F.,Fahmy, A. F. M.,Mahmoud, M.,Arief, M. H.,Elkoumy, M. A.

, p. 121 - 124 (2007/10/02)

Azides (IIa-c), prepared from the corresponding acid chlorides (Ia-c), on base-catalyzed decomposition with aromatic amines and aminobezoic acids give the corresponding N-aryl-N'-(phthalimidomethyl)ureas (IVa-u) via Curtius rearrangement.However, the base-catalyzed decomposition of II with hydrazines takes place via azido-group displacement to give the corresponding hydrazides (VIa-f).Lewis acid (AlCl3)-catalyzed decomposition of IIa-c in aromatic substrates gives N-aroylphthalimidomethyl amines (IXa-g).

On the preparation of N-phthalimidomethyl- and N-benzoic-acid-sulfimidomethyl-N-acylamines
