170452-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 170452-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,4,5 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 170452-98:
(8*1)+(7*7)+(6*0)+(5*4)+(4*5)+(3*2)+(2*9)+(1*8)=129
129 % 10 = 9
So 170452-98-9 is a valid CAS Registry Number.

A simple approach to 1',1'-a-methano carbocyclic thymidine
Ezzitouni,Barchi Jr.,Marquez
, p. 1345 - 1346 (1995)
An enantioselective synthesis of 1',1'a-methano carbocyclic thymidine, a rigid molecule that mimics thymidine's 2'-endo/3'-exo (South) conformation, is efficiently synthesized from chiral 2-benzyloxymethylcyclopent-3-enol.
