134303-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134303-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,3,0 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134303-97:
(8*1)+(7*3)+(6*4)+(5*3)+(4*0)+(3*3)+(2*9)+(1*7)=102
102 % 10 = 2
So 134303-97-2 is a valid CAS Registry Number.

Synthesis of new 2',3'-modified uridine derivatives from 2',3'-ene-2'-phenylselenonyl uridine by Michael addition reactions
Tong,Xi,Gioeli,Chattopadhyaya
, p. 3431 - 3450 (2007/10/02)
The synthetic utilities of 2',3'-ene-2'-phenylselenones 12 and 13 as synthetic equivalent of a dication [CH2+-CH2+] 5 have been demonstrated. They act as Michael acceptors, and undergo conjugate addition reactio
