Check Digit Verification of cas no
The CAS Registry Mumber 18827-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,2 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18827-81:
(7*1)+(6*8)+(5*8)+(4*2)+(3*7)+(2*8)+(1*1)=141
141 % 10 = 1
So 18827-81-1 is a valid CAS Registry Number.

A new convenient method for the high-yield synthesis of Ir4(CO)12
Pruchnik, F. P.,Wajda-Hermanowicz, K.,Koralewicz, M.
, p. 381 - 383 (1990)
The complex Ir4(CO)12 has been prepared by a new, simple method, involving heating of solutions of IrIII or IrIV chlorides in 98percent formic acid.Reaction at 100 deg C gave pure Ir4(CO)12 in 100percent yield.
