171357-27-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171357-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,3,5 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 171357-27:
(8*1)+(7*7)+(6*1)+(5*3)+(4*5)+(3*7)+(2*2)+(1*7)=130
130 % 10 = 0
So 171357-27-0 is a valid CAS Registry Number.

Synthesis of 2',3'-didehydro-2',3'-dideoxy nucleosides from 2',2'-bis(phenylthio) nucleoside analogs
Niihata,Kuno,Ebata,Matsushita
, p. 2327 - 2329 (2007/10/03)
2',3'-Didehydro-2',3'-dideoxy nucleosides were synthesized from 2',2'-bis(phenylthio) nucleoside analogs via five-step reactions. The sulfonyl group of the intermediate was removed by a treatment with sodium amalgam.
