163563-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163563-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,5,6 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163563-91:
(8*1)+(7*6)+(6*3)+(5*5)+(4*6)+(3*3)+(2*9)+(1*1)=145
145 % 10 = 5
So 163563-91-5 is a valid CAS Registry Number.

Stereoselective synthesis of (-)-ara-cyclohexenyl-adenine
Horváth, András,Ruttens, Bart,Herdewijn, Piet
, p. 3621 - 3623 (2008/02/02)
A stereoselective synthesis leading to (-)-ara-cyclohexenyl-adenine is described. The synthesis starts from methyl-α-d-glucopyranose and involves an isomerization step, selective protection/deprotection chemistry, a Ferrier rearrangement and a Mitsunobu r
