Check Digit Verification of cas no
The CAS Registry Mumber 12129-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,2 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12129-70:
(7*1)+(6*2)+(5*1)+(4*2)+(3*9)+(2*7)+(1*0)=73
73 % 10 = 3
So 12129-70-3 is a valid CAS Registry Number.

A general synthesis of homodinuclear μ-alkylidene complexes of tungsten, starting from Fischer type alkylidene complexes of tungsten is outlined.Thus the vinyl-alkylidene complexes (CO)5W=C(OMe)CHCHR react with (CO)5W=CPh2, as a source of coordinatively unsaturated w(CO)4, to give the dinuclear complexes W2(CO)9(OMe)CHCHR, and the complex (CO)5W=C(OMe)CHCH2 reacts slowly in hydrocarbon solution, in the absence of (CO)5W=CPh2, to give a dinuclear complex W2(CO)19C(OMe)CHCH2 in which the two metal centers are not bound together: this product is the result of coordination of the double bond of the starting material to a W(CO)5 species.
