Check Digit Verification of cas no

The CAS Registry Mumber 198148-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,1,4 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 198148-30:
(8*1)+(7*9)+(6*8)+(5*1)+(4*4)+(3*8)+(2*3)+(1*0)=170
170 % 10 = 0
So 198148-30-0 is a valid CAS Registry Number.

Cyclometallation of ferrocenylimines III. Regioselectivity in Hg(II) cyclometallated complexes

Wu, Yang Jie,Cui, Xiu Ling,Liu, Yuan Hong,Yuan, Han Zhen,Mao, Xi An

, p. 63 - 70 (2007/10/03)

The synthesis and mercuration of a series of Schiff bases 1′-benzoyl-1-[(arylimino)phenylmethyl]ferrocene (aryl: a variety of substituted phenyls) have been studied. In all cases the mercuration occurred at the 2-position of the ferrocene ring. Oxygen → mercury coordinated products were not obtained. The X-ray crystal structure of [2-chloromercurio-1-[((phenylimino)phenylmethyl)-1′-benzoyl] ferrocene 5c has been determined; this crystallizes in the monoclinic, space group P21/c with a =10.168(3), b= 16.105(3), c = 15,463(4)A, β = 103.61(2)° and Z = 4. Refinement of atomic parameters gave an R factor of 0.038 (Rω = 0.055) for 2440 unique reflections having 1>3σ(1). The structure confirms the formation of a five-membered metallocycle on the ferrocene moiety.
