64957-84-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64957-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,9,5 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 64957-84:
(7*6)+(6*4)+(5*9)+(4*5)+(3*7)+(2*8)+(1*4)=172
172 % 10 = 2
So 64957-84-2 is a valid CAS Registry Number.

We report a variety of synthetic strategies to access novel 4-cyanophenols bearing substituents expected to be resistant to metabolism.

Synthesis of Substituted Fluorenones and Substituted 3',3'-Dichlorospiro and Their Reactivities

Chew, Warren,Hynes, Rosemary C.,Harpp, David N.

, p. 4398 - 4404 (2007/10/02)

Several novel 9-fluorenones were synthesized and were used as precursors in an attempt to prepare unique substituted 3',3'-dichlorospiro.Several of the thiiranes were unstable and desulfurized during their preparation (7a-d, 11, 12). 3',3'-Dichloro(2,5-dimethoxyspiro (7f) was prepared along with 2,2-dichloro-3,3-bis(4-methoxyphenyl)thiirane (16), and 3',3'-dichloro-10,11-dihydrospirocycloheptane-5,2'-thiirane> (17) all of which were stable at room temperature.A study of the reactivity of fluorenyl-substituted thiiranes and other related thiiranes showed that the extent of aromaticity of the substituents at the 3-position of the thiiranes influences their stabilities.
