Check Digit Verification of cas no

The CAS Registry Mumber 64190-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,1,9 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64190-02:
(7*6)+(6*4)+(5*1)+(4*9)+(3*0)+(2*0)+(1*2)=109
109 % 10 = 9
So 64190-02-9 is a valid CAS Registry Number.

REACTIONS OF GROUP VIB HEXACARBONYLS WITH FORMAMIDINES.

De Roode,Vrieze

, p. 209 - 220 (1977)

The reaction of molybdenum and chromium hexacarbonyls with formamidines yields the tetrakis(formamidinato)dimolybdenum and dichromium complexes. In the case of molybdenum, a reaction scheme has been set up for the formation of these complexes. An interesting feature of the chemistry of these complexes is the reaction with Mo(CO)//6 or Cr(CO)//6 to yield novel complexes in which an ″M(CO)//3″ species is bound to one of the aromatic groups. Their physical and chemical properties are discussed. The reaction of W(CO)//6 with formamidine did not produce a complex analogous to that obtained with Mo(CO)//6 or Cr(CO)//6 but, instead, a deep purple colored complex.
