Check Digit Verification of cas no
The CAS Registry Mumber 91894-55-2 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, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91894-55:
(7*9)+(6*1)+(5*8)+(4*9)+(3*4)+(2*5)+(1*5)=172
172 % 10 = 2
So 91894-55-2 is a valid CAS Registry Number.

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
