Check Digit Verification of cas no

The CAS Registry Mumber 118464-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,6 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118464-69:
(8*1)+(7*1)+(6*8)+(5*4)+(4*6)+(3*4)+(2*6)+(1*9)=140
140 % 10 = 0
So 118464-69-0 is a valid CAS Registry Number.

Synthesis of various 3-substituted 1,2,4-oxadiazole-containing chiral β3- and α-amino acids from Fmoc-protected aspartic acid

Hamze?, Abdallah,Hernandez, Jean-Franc?ois,Fulcrand, Pierre,Martinez, Jean

, p. 7316 - 7321 (2003)

Various 3-substituted chiral 1,2,4-oxadiazole-containing Fmoc-β 3- and α-amino acids were synthesized from FmoC-(L or D)-Asp(OtBu)-OH and Fmoc-L-Asp-OtBu, respectively, in three steps (i.e., condensation of an aspartyl derivative with different

Synthesis of 3,5-disubstituted-1,2,4-oxadiazoles using tetrabutylammonium fluoride as a mild and efficient catalyst

Gangloff, Anthony R.,Litvak, Joane,Shelton, Emma J.,Sperandio, David,Wang, Vivian R.,Rice, Kenneth D.

, p. 1441 - 1443 (2007/10/03)

Tetrabutylammonium fluoride (TBAF) was found to be a mild and efficient catalyst for the synthesis of 3,5-disubstituted-1,2,4-oxadiazoles. Using 0.1 - 1.0 equivalents of TBAF in THF for 1 - 24 h at room temperature, alkanoyl- and aroyloxyamidines were converted in high yield to the corresponding 3,5-disubstituted-1,2,4-oxadiazoles. A variety of R and R′ substituents were investigated.
