Check Digit Verification of cas no

The CAS Registry Mumber 100367-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,6 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100367-04:
(8*1)+(7*0)+(6*0)+(5*3)+(4*6)+(3*7)+(2*0)+(1*4)=72
72 % 10 = 2
So 100367-04-2 is a valid CAS Registry Number.

Synthesis of Δ3-1-Methylene-1-carbacephems

Herdewijn, Piet,Claes, Paul J.,Vanderhaeghe, Hubert

, p. 661 - 664 (2007/10/02)

The total synthesis of (+/-)-1-methylene-2,2-dimethyl-7-amino-1-carbacephem-4-carboxylic acid (1) is described.The reaction scheme was essentially that described by Christensen et al. for the synthesis of (+/-)-1-carbacephems.In vitro antibacterial activities of the 7-phenoxyacetyl and 7-D-α-phenylglycyl derivatives of 1 were compared with those of 7-(phenoxyacetamido)desacetoxycephalosporanic acid and cefalexin.Derivatives of 1 were 2-4 times less active against most of the sensitive organisms than the corresponding 7-aminodesacetoxycephalosporanic acid analogues.The activity of the 7-D-α-phenylglycyl derivative of 1 however was about 20 times lower than that of cefalexin when measured against Staphylococcus aureus ATCC 6538P.
