Check Digit Verification of cas no

The CAS Registry Mumber 898528-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,5,2 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 898528-50:
(8*8)+(7*9)+(6*8)+(5*5)+(4*2)+(3*8)+(2*5)+(1*0)=242
242 % 10 = 2
So 898528-50-2 is a valid CAS Registry Number.

Synthesis of 4,4′-disubstituted azepines via ring-closing metathesis reaction and asymmetric arylation of lactones

Delhaye, Laurent,Merschaert, Alain,Diker, Khalid,Houpis, Ioannis N.

, p. 1437 - 1442 (2007/10/03)

The syntheses of the title compounds were accomplished via an original sequence of reactions including the ring-closing metathesis of ω-dienes by using the second-generation Grubbs' catalyst. The chiral diene precursors are available in racemic or optical
