Check Digit Verification of cas no

The CAS Registry Mumber 123792-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,9 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123792-42:
(8*1)+(7*2)+(6*3)+(5*7)+(4*9)+(3*2)+(2*4)+(1*2)=127
127 % 10 = 7
So 123792-42-7 is a valid CAS Registry Number.

SYNTHESIS OF BIS(ALKYLTHIO)BIPYRIDYLS BY NICKEL MEDIATED HOMO COUPLING OF HALOGENOPYRIDYL ALKYL SULPHIDES

Tiecco, M.,Tingoli, M.,Testaferri, L.,Bartoli, D.,Chianelli, D.

, p. 2857 - 2868 (1989)

The homo coupling of some halogenopyridyl t-butyl sulphides with Ni(O) complex, formed in situ from nickel(II) chloride, triphenylphosphine and zinc dust in DMF, afforded bis(t-butylthio)bipyridyls in moderate to good yield.These compounds were dealkylated by electron transfer with sodium in HMPA; the resulting thiolate anions were directly treated with methyl iodide and the bis(methylthio)bipyridyls were obtained.The dealkylation with a solution of sodium in HMPA afforded the mono anions which, after treatment with methyl iodide, gave the t-butylthio(methylthio)bipyridyls.
