197153-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197153-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,5 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 197153-86:
(8*1)+(7*9)+(6*7)+(5*1)+(4*5)+(3*3)+(2*8)+(1*6)=169
169 % 10 = 9
So 197153-86-9 is a valid CAS Registry Number.

Noe,Buchstaller,Haberhauer,Holzner
, p. 509 - 527 (2007/10/03)
The synthesis of protected 2′,3′-dideoxy-2′-hydroxymethyl nucleosides is presented. The nucleosides, obtained in a multi-step procedure starting from isopropylideneglycerol, may be used as building blocks for the synthesis of 2′,5′-ether linked oligonucleotides.
