263758-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263758-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,7,5 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 263758-81:
(8*2)+(7*6)+(6*3)+(5*7)+(4*5)+(3*8)+(2*8)+(1*1)=172
172 % 10 = 2
So 263758-81-2 is a valid CAS Registry Number.

Synthesis and properties of oligothymidylates incorporating an artificial bend motif
Seio, Kohji,Wada, Takeshi,Sekine, Mitsuo
, p. 162 - 180 (2007/10/03)
The uridylyl-(3' → 5')-thymidine dinucleotide block 14 (cUpdU), having a cyclic structure between the 2'-hydroxy of the upstream uridine and the 5- substituent of the downstream thymidine, was synthesized (Schemes 1 and 2). This cyclic structure is a stab
