60686-95-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60686-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,6,8 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 60686-95:
(7*6)+(6*0)+(5*6)+(4*8)+(3*6)+(2*9)+(1*5)=145
145 % 10 = 5
So 60686-95-5 is a valid CAS Registry Number.

A New Dihydrothiazine Ring Closure for the Preparation of 3-Methylcephalosporins from Azetidinone Disulfides at 5-10 deg

Davis, Michael,Wu, Wen-Yang

, p. 1519 - 1526 (2007/10/02)

p-Nitrobenzyl (2 R, 3 R)-2-(benzothiazol-2'-yldithio)-α-isopropenyl-4-oxo-3-phenoxyacetylamino-azetidine-1-acetate (3a), readily prepared from penicillin V, is smoothly cyclized by ammonium acetate in a dimethyl sulfoxide/tetrahydrofuran mixture at 5-10 deg to the ceph-3-em ester (2a) in high yield.Other ethers (3b-d), but not the free acid (3e), behave in a similar way.The ceph-3-em esters can be readily de-esterified to the free acid (2e).
