Check Digit Verification of cas no

The CAS Registry Mumber 80941-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,4 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80941-45:
(7*8)+(6*0)+(5*9)+(4*4)+(3*1)+(2*4)+(1*5)=133
133 % 10 = 3
So 80941-45-3 is a valid CAS Registry Number.

NEW SPIRO DERIVATIVES OF PENICILLIN

Chan, Lam,Matlin, Stephen A.

, p. 4025 - 4028 (2007/10/02)

The first example of carbenoid ring expansion of thiophene to a 2H-thiopyran has been observed in its Rh-catalysed reaction with benzhydryl 6-diazopenicillinate.Buchner ring expansion of anisole with the same carbenoid gives two isomeric methoxy-cycloheptatrienes by attact on the upper face of the β-lactam ring.In one of the isomers, the methoxyl group shows a strong conformational preference in solution, revealed by n.O.e. difference spectroscopy.
