Check Digit Verification of cas no

The CAS Registry Mumber 131853-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 131853-64:
(8*1)+(7*3)+(6*1)+(5*8)+(4*5)+(3*3)+(2*6)+(1*4)=120
120 % 10 = 0
So 131853-64-0 is a valid CAS Registry Number.

Nucleoside 3'-N,N-dialkylphosphonamidates: Novel building blocks for oligonucleotide synthesis

Wada,Ishikawa,Hata

, p. 6363 - 6366 (1990)

Nucleoside 3'-N,N-diisopropylphosphonamidates reacted with tris(2,4,6-tribromophenoxy)dichlorophosphorane (BDCP) to generate the corresponding aminophosphorochloridites without cleavage of the P-N bond. The reaction was applied to internucleotidic bond formation.

Nucleoside 3'-N,N-Dialkylphosphonamidates as Novel Nucleotide Units for the Solution-Phase Oligonucleotide Syntheis

Wada, Takeshi,Ishikawa, Kazushige,Hata, Tsujiaki

, p. 2043 - 2054 (2007/10/02)

Nucleoside 3'-N,N-diisopropylphosphonamidate building blocks for oligonucleotide syntheis were prepared in high yields from appropriately protected nucleosides by use of chlorobis(N,N-diisopropylamino)phosphine as a phosphitylating reagent.The 5'-dimethox
