926640-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 926640-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,6,6,4 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 926640-49:
(8*9)+(7*2)+(6*6)+(5*6)+(4*4)+(3*0)+(2*4)+(1*9)=185
185 % 10 = 5
So 926640-49-5 is a valid CAS Registry Number.

Nickel-catalysed addition of dialkylzinc reagents to N-phosphinoyl- and N-sulfonylimines
Almansa, Raquel,Guijarro, David,Yus, Miguel
, p. 1167 - 1174 (2007/10/03)
A catalytic amount of a nickel complex (0.1-5.3 mol %) extraordinarily increases the reaction rate of the addition of dialkylzinc reagents to N-(diphenylphosphinoyl)- or N-(benzenesulfonyl)imines. The reaction of imines derived from both aromatic and alip
