Check Digit Verification of cas no

The CAS Registry Mumber 49638-94-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 49638-94:
(7*4)+(6*9)+(5*6)+(4*3)+(3*8)+(2*9)+(1*4)=170
170 % 10 = 0
So 49638-94-0 is a valid CAS Registry Number.

α-Aminoalkyl-4-hydroxy-3-alkylsulfonylmethylbenzyl alcohols having β-adrenergic stimulant activity

-

, (2008/06/13)

α-Aminoalkyl-4-hydroxy-3-alkylsulfonylmethylbenzyl alcohols having β-adrenergic stimulant activity, particularly as selected bronchodilators, are prepared from 4-hydroxyphenones by conversion to a 3-alkylsulfonylmethylphenone, bromination of these phenones and treatment of the resulting α-bromo derivatives with an N-benzyl secondary amine, followed by catalytic hydrogenation to remove the benzyl groups and reduce the ketone moiety.

, (2008/06/13)

N,N'-Bis 2-(3-substituted-4-hydroxyphenyl)-ethyl or-2-hydroxyethyl!-polymethylenediamines having β-adrenergic stimulant activity particularly as selective bronchodilators, are prepared generally by condensation of an N-benzylphenethylamine with a polymethylene dihalide or by reaction of an α-bromoacetophenone with an N,N'-dibenzyl-polymethylenediamine, with further operations depending on the nature of the 3-substituent, and subsequently hydrogenating catalytically with for example palladium-on-carbon. The key intermediates are also part of the invention.
