Check Digit Verification of cas no

The CAS Registry Mumber 91626-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,2 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91626-66:
(7*9)+(6*1)+(5*6)+(4*2)+(3*6)+(2*6)+(1*6)=143
143 % 10 = 3
So 91626-66-3 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).
