123689-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123689-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,6,8 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123689-97:
(8*1)+(7*2)+(6*3)+(5*6)+(4*8)+(3*9)+(2*9)+(1*7)=154
154 % 10 = 4
So 123689-97-4 is a valid CAS Registry Number.

, p. 3811 - 3812 (2007/10/02)
A novel carbon-carbon bond formation, i.e. ethylation at the α-position of the nitrile was occurred in the bakers' yeast reduction of cyanoacetone, to give optically pure (3S)-3-hydroxy-2-ethylbutyronitrile.
