Check Digit Verification of cas no

The CAS Registry Mumber 111508-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,5,0 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 111508-44:
(8*1)+(7*1)+(6*1)+(5*5)+(4*0)+(3*8)+(2*4)+(1*4)=82
82 % 10 = 2
So 111508-44-2 is a valid CAS Registry Number.

Rhodium Carbenoid Mediated Cyclisations. Synthesis of 1,2-Diazetidinones (Aza-β-lactams).

Lawton, Geoffrey,Moody, Christopher J.,Pearson, Christopher J.

, p. 899 - 902 (2007/10/02)

Decomposition of the diazo hydrazides (1b-h) in boiling benzene in the presence of a catalytic amount of rhodium(II) acetate gives the corresponding 1,2-diazetidinones (2) in good yield.The aza-β-lactams (2) exhibit the expected high frequency carbonyl st
