125486-31-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125486-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,8 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125486-31:
(8*1)+(7*2)+(6*5)+(5*4)+(4*8)+(3*6)+(2*3)+(1*1)=129
129 % 10 = 9
So 125486-31-9 is a valid CAS Registry Number.

SYNTHESIS OF N,N,9-TRISUBSTITUTED ADENINES UNDER CONDITIONS OF PHASE-TRANSFER CATALYSIS

Ramzaeva, N. P.,Gol'dberg, Yu. Sh.,Alksnis, E. R.,Lidak, M. Yu.,Shimanskaya, M. V.

, p. 1611 - 1615 (2007/10/02)

Alkylation of N-mono- and N,N-disubstituted adenines by 2,6-dichlorobenzyl chlorides under the conditions of phase-transfer catalysis in the benzene-50percent aqueous sodium hydroxide system takes place regioselectively with the formation of the corresponding N,N,9-trisubstituted adenines (60-80percent).The isomeric N,N,3-trisubstituted adenines are also formed.The N,9-disubstituted adenines are alkylated regiospecifically under analogous conditions and give N,N,9-trisubstituted adenines with quantitative yields.
