62801-92-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62801-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,8,0 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 62801-92:
(7*6)+(6*2)+(5*8)+(4*0)+(3*1)+(2*9)+(1*2)=117
117 % 10 = 7
So 62801-92-7 is a valid CAS Registry Number.

A Method for the Preparation of 7α-Methoxycephalosporins

Morimoto, Akira,Matsushita, Yoshihiro,Ochiai, Michihiko

, p. 1109 - 1113 (2007/10/02)

A method for the preparation of 7α-methoxycephalosporins has been developed. 7β-Phosphoramidodeacetoxycephalosporin (6) and 7β-phosphoramidocephalosporin (14) obtained from the 7β-amino-derivatives (5) and (13), were converted into 7α-methoxy-7β-phosphoramidodeacetoxycephalosporin (7) and 7α-methoxy-7β-phosphoramidocephalosporin (15), respectively, by reaction with LiOMe and ButOCl.Treatment of (7) with BunLi and Et3N followed by acylation with phenylacetyl chloride gave 7α-methoxy-7β-phenylketenimino-derivative (11), which were easily hydrated to 7α-methoxy-7β-(phenylacetamido)deacetoxycephalosporin (12).Treatment of (15) under similar conditions afforded, contrary to the result obtained with (7), 7α-methoxy-7β-(phenylacetamido)cephalosporin (16), without any of the corresponding ketenimine.This method was also successfully applied to the synthesis of 6α-methoxypenicillins.
