123131-51-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123131-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,3 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123131-51:
(8*1)+(7*2)+(6*3)+(5*1)+(4*3)+(3*1)+(2*5)+(1*1)=71
71 % 10 = 1
So 123131-51-1 is a valid CAS Registry Number.

Reactions of 5-bromo substituted pyrimidine nucleosides with aqueous alkalies: kinetics and mechanisms.
K?ppi,L?nnberg
, p. 768 - 775 (2007/10/02)
Kinetics for the parallel and consecutive steps of the reactions of 5-bromocytidine, 5-bromouridine and its 5'-O-methyl and 2',3'-O-isopropylidene derivatives with aqueous alkalies were studied by LC. The mechanisms of the partial reactions involved are discussed.
