Check Digit Verification of cas no

The CAS Registry Mumber 77321-83-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,2 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77321-83:
(7*7)+(6*7)+(5*3)+(4*2)+(3*1)+(2*8)+(1*3)=136
136 % 10 = 6
So 77321-83-6 is a valid CAS Registry Number.

POLYCHLOROPHENYL-PLATINUM(II) COMPLEXES CONTAINING TRIPHENYLPHOSPHINE

Rossell, O.,Sales, J.,Seco, M.

, p. 133 - 137 (1981)

A new method to prepare compounds of the type trans- (R = C6H5; 2,5-C6H3Cl2; 2,3,4-, and 2,4,6-C6H2Cl3; 2,3,4,5-, 2,3,4,6- and 2,3,5,6-C6HCl4 and C6Cl5) by reaction of cis- and HgR2 in the molten state is described.The reactions of the complexes with HCl, Cl2 and I2 have been examined in order to give information about the relative ease of cleavage of the various Pt- aryl bonds.The replacement of Cl by NCS suggests an associative mechanism even for the complexes in which the polychlorophenyl ligand has chlorine atoms in both ortho positions.
