132120-37-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132120-37-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,2 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132120-37:
(8*1)+(7*3)+(6*2)+(5*1)+(4*2)+(3*0)+(2*3)+(1*7)=67
67 % 10 = 7
So 132120-37-7 is a valid CAS Registry Number.

supporting information, p. 6614 - 6617 (2017/12/26)

A phenyliodine(III) diacetate mediated umpolung reactivity of the tertiary amines with suitably substituted o-hydroxybenzyl and phenyl groups is exploited to facilitate o-C(sp2)-H functionalization to afford diaryl ethers. The presence of an o-

Synthesis of new benzoxazaphosphinine/benzoxazaphosphole/ diazaphosphaphenalene-2-sulfides using Lawesson's reagent

Prasad, G. Syam,Babu, B. Hari,Reddy, C. Devendranath,Raju, C. Naga,Reddy, C. Suresh

, p. 85 - 91 (2008/03/14)

Synthesis of new benzoxazaphosphinine/benzoxazaphosphole/ diazaphosphaphenalene 2-sulfides were accomplished by the reaction of Lawesson's reagent (LR) with 4-bromo-2-[(phenylamino) methyl]phenol (1a), 4-bromo-2-[(4-chloro/bromo/methoxy/methylphenyl-amino)methyl]phenol (1b-e), 4-bromo-2-[(benzylamino)methyl]phenol (1f), 2-amino-4-chlorophenol (2a)/2-amino-4-methylphenol (2b), 1,8-diaminonaphthalene (3) respectively in anhydrous toluene. Products 4a-f, 5a-b and 6 were characterized by IR, 1H, 13C, 31P NMR and Mass spectra. Copyright Taylor & Francis Group, LLC.
