62401-70-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62401-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,0 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 62401-70:
(7*6)+(6*2)+(5*4)+(4*0)+(3*1)+(2*7)+(1*0)=91
91 % 10 = 1
So 62401-70-1 is a valid CAS Registry Number.

Synthesis of bronchospasmolytically effective β phenylethyl aminoalkyl xanthines
Klingler
, p. 4 - 14 (2007/10/05)
New theophylline and theobromine derivatives are synthesized from the β phenylethylaminoalkyl xanthines, whose phenyl substituent is substituted by one or two hydroxyl groups and partially also by other substituents. Different methods of synthesis are described, among them the production of the bronchospasmolytic 7 (3 [2 (3,5 dihydroxyphenyl) 2 hydroxy ethylamino] propyl) theophylline (reproterol . HCl).
