139068-96-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139068-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,6 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139068-96:
(8*1)+(7*3)+(6*9)+(5*0)+(4*6)+(3*8)+(2*9)+(1*6)=155
155 % 10 = 5
So 139068-96-5 is a valid CAS Registry Number.

(-)-δ-N-Normethylskytanthine (1) has been synthsised from (1R,4R,1'S)-2-(phenylethyl)-2-azabicyclohept-5-ene (2) which undergoes a ketene-amino-Claisen rearrangement by reaction with dichloroketene to generate (1S,6R,1'S)-3-(phenylethyl)-5,5-dichlo
