85548-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85548-93-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,4 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85548-93:
(7*8)+(6*5)+(5*5)+(4*4)+(3*8)+(2*9)+(1*3)=172
172 % 10 = 2
So 85548-93-2 is a valid CAS Registry Number.

7&α- or 7&β-(4-Phenylbutyl)dihydrocodeine Derivatives
Leland, David L.,Kotick, Michael P.
, p. 1813 - 1819 (2007/10/02)
A lipophilic 4-phenylbutyl group was selectively incorporated into the 7α- or 7β-position of the morphine nucleus by use of 6,7-oxymethylene (oxetane) intermediates. 7,7-Bisdihydroisocodeine (2) with dilute NaOH gave 6β,7β-(oxymethylene)
