68090-03-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68090-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,9 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68090-03:
(7*6)+(6*8)+(5*0)+(4*9)+(3*0)+(2*0)+(1*3)=129
129 % 10 = 9
So 68090-03-9 is a valid CAS Registry Number.

Reduction of selenoamides to amines using SmI2-H2O

Thurow, Samuel,Lenardo, Eder J.,Just-Baringo, Xavier,Procter, David J.

supporting information, p. 50 - 53 (2017/11/28)

Selenoamides are selectively reduced to amines by SmI2 with H2O. The process is general for primary, secondary, and tertiary aryl and alkyl selenoamide substrates and selectively delivers amine products. The reduction proceeds under mild conditions using SmI2 activated by straightforward addition of H2O, and does not require an additional Lewis base additive.

Synthesis of primary arylselenoamides by reaction of aryl nitriles with Woollins' reagent

Hua, Guoxiong,Li, Yang,Slawin, Alexandra M. Z.,Woollins, J. Derek

, p. 5251 - 5254 (2007/10/03)

The reaction of aryl nitriles with Woollins' reagent followed by water affords a variety of primary arylselenoamides In 60-100% yield. The first crystal structures of two primary selenoamides are reported.

A facile preparation of aliphatic and aromatic primary selenoamides using 4-methylselenobenzoate as a new selenating reagent

Ishihara, Hideharu,Yosimura, Katsuhiro,Kouketsu, Mamoru

, p. 1287 - 1288 (2007/10/03)

Aliphatic and aromatic primary selenoamides 2 were isolated by the reaction of the corresponding aliphatic and aromatic nitriles with potassium 4-methylselenobenzoate in the presence of BF3·Et2O in moderate from high yields.
