1440611-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440611-08-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,6,1 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1440611-08:
(9*1)+(8*4)+(7*4)+(6*0)+(5*6)+(4*1)+(3*1)+(2*0)+(1*8)=114
114 % 10 = 4
So 1440611-08-4 is a valid CAS Registry Number.

Process for the Production of Seven-Membered Lactam Morphinans
-
Paragraph 0110, (2013/06/26)
The present invention relates to improved processes for preparing lactam morphinans. The processes generally transform keto-morphinans to seven-membered lactam morphinans using a hydroxyamine sulfonic acid reagent and proceed in high yield and with good selectivity.
