121469-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121469-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,6 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121469-98:
(8*1)+(7*2)+(6*1)+(5*4)+(4*6)+(3*9)+(2*9)+(1*8)=125
125 % 10 = 5
So 121469-98-5 is a valid CAS Registry Number.

He, Kaizhang,Sergueev, Dmitri S.,Sergueeva, Zinaida A.,Shaw, Barbara Ramsay
, p. 4601 - 4604 (1999)
Diuridine 3',5'-boranophosphate, the RNA analogue of boranophosphate nucleic acids, was synthesized by a new approach via the H-phosphonate. Two diastereomers of diuridine 3',5'-boranophosphate were separated by reverse phase HPLC.
