1265139-81-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1265139-81-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,1,3 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1265139-81:
(9*1)+(8*2)+(7*6)+(6*5)+(5*1)+(4*3)+(3*9)+(2*8)+(1*1)=158
158 % 10 = 8
So 1265139-81-8 is a valid CAS Registry Number.

Ceric ammonium nitrate-mediated detritylation of tritylated amines
Pattanayak, Sankha,Sinha, Surajit
, p. 34 - 37 (2011)
Efficient deprotection of tritylated amines to the corresponding amines mediated by 20 mol % ceric ammonium nitrate [Ce(NH4) 2(NO3)6, CAN], 10 equiv of acetic acid and 15 equiv of water in dichloromethane is presented. This method equally worked well in the case of morpholino nucleosides.
