134100-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134100-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134100-25:
(8*1)+(7*3)+(6*4)+(5*1)+(4*0)+(3*0)+(2*2)+(1*5)=67
67 % 10 = 7
So 134100-25-7 is a valid CAS Registry Number.

Nucleosidic enol esters: A versatile tool for the synthesis of 3'-carbon-substituted nucleosides
Haraguchi,Tanaka,Itoh,Miyasaka
, p. 777 - 780 (1991)
Enol esters of uracil and adenine nucleosides prepared by selenoxide fragmentation of the corresponding 3'-phenylseleno derivatives have been shown to yield 3'-carbon-substituted products upon reacting with MeLi followed by electrophiles, providing the fi
