119705-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119705-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,0 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119705-21:
(8*1)+(7*1)+(6*9)+(5*7)+(4*0)+(3*5)+(2*2)+(1*1)=124
124 % 10 = 4
So 119705-21-4 is a valid CAS Registry Number.

Study of the reactivity of CpMCo(CO)7 (M = Mo, W) complexes toward various alkynes
Yanez,Lugan,Mathieu
, p. 2998 - 3001 (2008/10/08)
The CpMCo(CO)7 complexes (M = Mo, W) react with alkynes in boiling hexane, leading to CpMCo(CO)5(μ-η2,η2-RC≡CR′) complexes (M = Mo, R = R′ = H, Ph, SiMe3, C(O)OMe; M = Mo, R = H, R′ = SiMe3
