142644-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142644-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,4 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142644-81:
(8*1)+(7*4)+(6*2)+(5*6)+(4*4)+(3*4)+(2*8)+(1*1)=123
123 % 10 = 3
So 142644-81-3 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
