89766-18-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89766-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,6 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89766-18:
(7*8)+(6*9)+(5*7)+(4*6)+(3*6)+(2*1)+(1*8)=197
197 % 10 = 7
So 89766-18-7 is a valid CAS Registry Number.

Studies related to β-lactam antibiotics. IX. Alcoholysis of a 4-oxa-1-azabicyclo[3.2.0]heptane-3,7-dione

Sako,Akira,Hirota,Maki

, p. 4539 - 4542 (1983)

Thermal reactions of (2R, 5S, 6S)-2-(1-methylethenyl)-6-phenylacetamido-4-oxa-1-azabicyclo[3.2.0]heptane -3,7-dione (1) with alcohols gave 2-phenylmethyl-4-→N-[(1R)-1-carboxy-2-methylprop-2-enyl]←carbamoyloxazol e (2a), (3S, 4S)-4-alkoxy-1-[(1R)-1-carboxy-2-methylprop-2-enyl]-3-phenylacetamidoazeti din-2-ones (3a, c), and (2S)-N-[(1R)-1-carboxy-2-methylprop-2-enyl]-3,3-dialkoxy-2-phenylacetamido propionamides (4a, c), probably via an intramolecular ring transformation of 1 into (1S, 5R)-3-phenylmethyl-6-[(1R)-1-carboxy-2-methylprop-2-enyl]-4-oxa-2,6-diazab icyclo[3.2.0]hept-2-en-7-one (5a) in the initial stage of the reaction.
