1393735-89-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1393735-89-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,7,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1393735-89:
(9*1)+(8*3)+(7*9)+(6*3)+(5*7)+(4*3)+(3*5)+(2*8)+(1*9)=201
201 % 10 = 1
So 1393735-89-1 is a valid CAS Registry Number.

Stereoselective syntheses of 3-dehydroxynaltrexamines and N-methyl-3-dehydroxynaltrexamines
Li, Mengchu,St. Onge, Celsey M.,Zhang, Yan
, (2020)
Methodology is presented for the synthesis of 6α/β-3-dehydroxynaltrexamines and 6α/β-N-methyl-3-dehydroxynaltrexamines. A stereoselective route is provided for each target compound while a novel one-pot method for the synthesis of 6α/β-N-methyl-3-dehydrox
