Check Digit Verification of cas no

The CAS Registry Mumber 129725-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,2 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129725-99:
(8*1)+(7*2)+(6*9)+(5*7)+(4*2)+(3*5)+(2*9)+(1*9)=161
161 % 10 = 1
So 129725-99-1 is a valid CAS Registry Number.

Reactions between Bis(O-alkyl dithiocarbonato)nickel(II) Complexes and Phosphines. Formation of a Dithiocarbonate Complex of Nickel(II):

Perpinan, Maria F.,Ballester, Loreto,Gonzalez-Casso, Maria E.,Santos, Amelia

, p. 281 - 284 (1987)

The behaviour of O-alkyl dithiocarbonato complexes, , towards several phosphines has been studied.Depending on the S2COR derivative and phosphine (L) used, octahedral complexes , paramagnetic five-co-ordinate complexes , and square-planar (R=Et or cyclo-C6H11) and complexes have been obtained.The reaction of (R=Me, Et, or cyclo-C6H11) with an excess of dppe gives which is the first NiII-dithiocarbonate complex described.This compound reacts with MeI and C3H5Br to give (X=I or Br).There is no reaction with Lewis-base N donors or with carbon monoxide.
