133910-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133910-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,1 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133910-57:
(8*1)+(7*3)+(6*3)+(5*9)+(4*1)+(3*0)+(2*5)+(1*7)=113
113 % 10 = 3
So 133910-57-3 is a valid CAS Registry Number.

Efficient amide-directed catalytic asymmetric hydroboration
Smith, Sean M.,Thacker, Nathan C.,Takacs, James M.
, p. 3734 - 3735 (2008/09/20)
A series of acyclic β,γ-unsaturated amides are shown to undergo highly regio- (>95%) and enantioselective (93-99% ee) rhodium-catalyzed hydroboration with pinacolborane (PinBH) using simple chiral monophosphite or phosphoramidite ligands in combination wi
