Check Digit Verification of cas no

The CAS Registry Mumber 301150-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,1,1,5 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 301150-85:
76 % 10 = 6
So 301150-85-6 is a valid CAS Registry Number.

Catalytic approaches to the synthesis of β-lactamase inhibitors

Buynak, John D.,Doppalapudi, Venkata Ramana,Frotan, Mohammed,Kumar, Ramon,Chambers, Alison

, p. 5709 - 5718 (2000)

Catalytic couplings were utilized to stereospecifically synthesize several 7E- and 7Z-alkylidenecephalosporins. Members of this class are known inhibitors of β-lactamase. Zinc/NH4Cl reduction of dibromide 14 stereospecifically produced E-monobromide, 15. In contrast, treatment of 14 with isopropylmagnesium bromide, followed by mild acid, stereospecifically produced Z-monobromide 27. These reactions involve stable, intermediate α-(metalloalkylidene)-β-lactams. Monobromides 15 and 27 were stereospecifically coupled to organostannanes, or were converted to the corresponding organostannanes, 22 and 32, which coupled with organohalides.
