Check Digit Verification of cas no

The CAS Registry Mumber 87568-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,6 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87568-64:
(7*8)+(6*7)+(5*5)+(4*6)+(3*8)+(2*6)+(1*4)=187
187 % 10 = 7
So 87568-64-7 is a valid CAS Registry Number.

Synthesis of β-lactam antibiotics by the sulfeno-cycloamination

Ihara,Haga,Yonekura,et al.

, p. 7345 - 7352 (2007/10/02)

A novel efficient beta -lactam synthesis was achieved by two successive processes (sulfeno-cycloamination), addition of phenysulfenyl chloride to alpha , beta -unsaturated amides followed by base treatment. Key synthetic intermediates of monobactams and nocardicin derivatives were obtained via this method. construction of the 1-carbapenam ring system by the sulfenocycloamination is also described.
