2147-15-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2147-15-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2147-15:
(6*2)+(5*1)+(4*4)+(3*7)+(2*1)+(1*5)=61
61 % 10 = 1
So 2147-15-1 is a valid CAS Registry Number.

PROTECTION OF 5'-TERMINAL PHOSPHATE OF DEOXYRIBOOLIGONUCLEOTIDES BY USE OF o,o'-DIAMINOBIPHENYL
Nishizawa, Makoto,Kurihara, Takashi,Hata, Tsujiaki
, p. 175 - 178 (2007/10/02)
Cyclic phosphorodianilidate derivatives of nucleoside 5'-phosphates were prepared by use of triphenylphosphine and 2,2'-dipyridyl disulfide as condensing agent and used for the synthesis of oligodeoxyribonucleotides.Removal of the diamino group was remarkably accelerated by coaddition of AgOAc and acid anhydrides to the conventional system, iAmONO-pyridine-AcOH.
