Check Digit Verification of cas no

The CAS Registry Mumber 128315-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,1 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128315-97:
(8*1)+(7*2)+(6*8)+(5*3)+(4*1)+(3*5)+(2*9)+(1*7)=129
129 % 10 = 9
So 128315-97-9 is a valid CAS Registry Number.

SYNTHESIS OF HALOGEN-CONTAINING 1-(DIPHENYLMETHYLENE)-2(1H)-NAPHTHALENONE

Chumachenko, N. V.,Kolesnikov, V. T.,Novikov, V. P.,Pirozhenko, V. V.

, p. 317 - 320 (2007/10/02)

The reaction of 1-(diphenylmethylene)-2(1H)-naphthalenone with chlorine or bromine leads to 3,4-dihalogeno-3,4-dihydro-1-(diphenylmethylene)-2(1H)-naphthalenones.The latter are capable of eliminating the hydrogen halide with the formation of 3-halogeno-1-
