Calculate Digit Verification of CAS Registry Number 1026812-13:
(9*1)+(8*0)+(7*2)+(6*6)+(5*8)+(4*1)+(3*2)+(2*1)+(1*3)=114
114 % 10 = 4
So 1026812-13-4 is a valid CAS Registry Number.

Synthesis and structure of the marine ascidian 8-oxoadenine aplidiamine

Itaya, Taisuke,Hozumi, Yoshitaka,Kanai, Tae,Ohta, Tomihisa

, p. 1297 - 1300 (2007/10/03)

Alkylation of 8-oxoadenosine (13) with 4-benzyloxy-3,5-dibromobenzyl bromide (20), followed by Dimroth rearrangement and acid hydrolysis, provided N-(3,5-dibromo-4-hydroxybenzyl)-8-oxoadenosine (15). The 2'- deoxy version of this reaction sequence accomplished the first synthesis of N-(3,5-dibromo-4- hydroxybenzyl)-8-oxoadenine (16), which is the correct expression for marine ascidian purine aplidiamine.
