157042-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157042-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,4 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 157042-73:
(8*1)+(7*5)+(6*7)+(5*0)+(4*4)+(3*2)+(2*7)+(1*3)=124
124 % 10 = 4
So 157042-73-4 is a valid CAS Registry Number.

Gold(I)-catalyzed asymmetric aldol reactions of fluorinated benzaldehydes with an α-isocyanoacetamide
Soloshonok,Hayashi
, p. 1091 - 1094 (1994)
The use of N,N-dimethyl-α-isocyanoacetamide instead of methyl α-isocyanoacetate in the gold(I)-catalyzed asymmetric aldol reactions with polyfluorinated benzaldehydes was found to improve both diastereo- and enantioselectivity in the formation of trans-ox
