122689-92-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122689-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,8 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122689-92:
(8*1)+(7*2)+(6*2)+(5*6)+(4*8)+(3*9)+(2*9)+(1*2)=143
143 % 10 = 3
So 122689-92-3 is a valid CAS Registry Number.

CYCLOPEPTIDE ALKALOID MODEL STUDIES. A TWO-STEP CONVERSION OF 5-AMINOISOXAZOLES TO AMINO ACID BIS-AMIDES
Lipshutz, Bruce H.,Reuter, Deborah C.
, p. 6067 - 6070 (2007/10/02)
Thermolyses of substituted 5-aminoisoxazoles, readily available from common starting materials, lead to azirines in good yields.Subsequent hydration affords bis-amide derivatives of amino acids.
