121481-90-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121481-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,8 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121481-90:
(8*1)+(7*2)+(6*1)+(5*4)+(4*8)+(3*1)+(2*9)+(1*0)=101
101 % 10 = 1
So 121481-90-1 is a valid CAS Registry Number.

Synthesis of novel N-cyclopentenyl-lactams using the Aubé reaction

Shinde, Madhuri V.,Ople, Rohini S.,Sangtani, Ekta,Gonnade, Rajesh,Reddy, D. Srinivasa

supporting information, p. 1060 - 1067 (2015/08/18)

A novel and convenient method utilizing the Aubé reaction to access a new class of compounds that are similar to carbocyclic nucleosides is reported. The azido alcohol derived from Vince lactam undergoes the Aubé reaction with various cyclic ketones to gi

Deamination of 9-(hydroxymethylated cycloalkyl)-9H-adenines (carbocyclic adenine nucleosides) by adenosine deaminase: Effect of high-pressure upon deamination rate and enantioselectivity

Katagiri, Nobuya,Ito, Yumiko,Shiraishi, Takuya,Maruyama, Tokumi,Sato, Yoshiko,Kaneko, Chikara

, p. 631 - 647 (2007/10/03)

The deamination of eight kinds of racemic carbocyclic adenine nucleosides by adenosine deaminase under high-pressure (400 MPa) was examined and the result was compared with that obtained from the reaction under atmospheric pressure. The deamination of all

Synthesis of carbocyclic nucleosides from 2-azabicyclo[2.2.1]hept-5-en-3-ones: Sodium borohydride-mediated carbon-nitrogen bond cleavage of five- and six-membered lactams

Katagiri,Muto,Nomura,Higashikawa,Kaneko

, p. 1112 - 1122 (2007/10/02)

Various carbocyclic ribofuranosyl nucleosides were stereoselectively synthesized through a small number of steps from 2-azabicyclo[2.2.1]hept-5-en-3-ones by the use of sodium borohydride-mediated C-N bond cleavage as a key step. Ready availability of a no
