153683-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153683-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,6,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153683-83:
(8*1)+(7*5)+(6*3)+(5*6)+(4*8)+(3*3)+(2*8)+(1*3)=151
151 % 10 = 1
So 153683-83-1 is a valid CAS Registry Number.

1-(Alkyl- or aryl-sulfinyl)naphthalenes activated by electron-withdrawing substituents at the 2-position undergo substitution reactions on treatment with Grignard reagents.Evidence suggesting that these transformations proceed through ligand-coupling reactions of ?-sulfuranes is presented.The ligand-coupling reaction of homochiral sulfoxides with 1-naphthylmagnesium bromide furnishes atropisomeric 1,1'-binaphthyls in 60-95percent ee.Single-crystal X-ray structure determinations have been carried out on 2-(thiophen-3-yl>amino)-2-methylpropan-1-ol 18 and 2-(2-hydroxy-1,1-dimethylethyl)-2,3-dihydronaphthoisothiazol-3-one 22, compounds formed through intramolecular nucleophilic and electrophilic attack, respectively, on a neighbouring oxazoline group.The absolute configuration of (R)-(+)-1-(tert-butylsulfinyl)naphthalene 27 was determined by a single-crystal X-ray study of the 2-bromo-derivative 28.
