Check Digit Verification of cas no

The CAS Registry Mumber 72301-66-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,0 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72301-66:
(7*7)+(6*2)+(5*3)+(4*0)+(3*1)+(2*6)+(1*6)=97
97 % 10 = 7
So 72301-66-7 is a valid CAS Registry Number.

Simple Synthesis of Aryl p-Nitroarylacetonitriles by Vicarious Nucleophilic Substitution with Carbanions of Protected Cyanohydrins

Rad, Nazar,M?kosza, Mieczys?aw

, p. 376 - 380 (2018/01/27)

Acetals of the cyanohydrins of aromatic aldehydes were deprotonated to generate carbanions, which were used in the vicarious nucleophilic substitution of the hydrogen atom of aromatic and heteroaromatic nitro compounds to form p-nitro-substituted diarylac

Vicarious Substitution of Hydrogen in Aromatic Nitro Compounds with Acetonitrile Derivatives

Makosza, Mieczyslaw,Winiarski, Jerzy

, p. 1534 - 1535 (2007/10/02)

Carbanions of α-phenoxy and thioalkoxy nitriles substitute hydrogen in the para or ortho position of aromatic nitro compounds, giving nitroarylacetonitriles in a process in which phenolate or thiolate anions are vicarious leaving groups.
