91894-60-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91894-60-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91894-60:
(7*9)+(6*1)+(5*8)+(4*9)+(3*4)+(2*6)+(1*0)=169
169 % 10 = 9
So 91894-60-9 is a valid CAS Registry Number.

SYNTHESIS OF 7-β-HYDROXYPHENETHYL-8-BENZYLAMINOTHEOPHYLLINE AND SOME OF ITS DERIVATIVES
Pawlowski, Maciej
, p. 461 - 465 (2007/10/02)
An efficient synthesis of 7-β-hydroxyphenethyl-8-benzyl-, N-benzyl-N-ethyl-, dibenzylaminotheophyllines (2-4) by addition of styrene oxide to the corresponding 8-substituted theophyllines was elaborated.It has been found that reaction between 7-β-hydroxyp
