Check Digit Verification of cas no

The CAS Registry Mumber 221908-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,9,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 221908-31:
(8*2)+(7*2)+(6*1)+(5*9)+(4*0)+(3*8)+(2*3)+(1*1)=112
112 % 10 = 2
So 221908-31-2 is a valid CAS Registry Number.

Synthesis, characterization and reactivity of the ω-haloalkyl complexes [(η5-C5R5)W(CO)3{(CH2)nX}] (R=H, n=3-7, X=Br and I; R=CH3, n=3, 4, X=Br and I)

Yin, Xiaolong,Moss, John R.

, p. 252 - 266 (1999)

The new ω-bromoalkyl tungsten complexes [CpW(CO)3{(CH2)nBr}] (n=5-7) and [Cp*W(CO)3{(CH2)nBr}] (n=4) were prepared in good yields by the reactions of Na[CpW(CO)3] or Na[Cp*W(CO)
