1215227-04-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1215227-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,2,2 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1215227-04:
(9*1)+(8*2)+(7*1)+(6*5)+(5*2)+(4*2)+(3*7)+(2*0)+(1*4)=105
105 % 10 = 5
So 1215227-04-5 is a valid CAS Registry Number.

Cobalt-catalyzed asymmetric hydrovinylation
Vogt, Dieter
, p. 7166 - 7168 (2010)
(Chemical equation presented) Back to the first row: A surprisingly simple protocol involving chiral diphosphine complexes of cobalt(II) salts allows the highly enantioselective hydrovinylation of 1,3-dienes in extremely high selectivities and yields.
