91603-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91603-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,0 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91603-27:
(7*9)+(6*1)+(5*6)+(4*0)+(3*3)+(2*2)+(1*7)=119
119 % 10 = 9
So 91603-27-9 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS OF CIS-2-SUBSTITUTED CYCLOHEXANAMINES WITH HIGHT OPTICAL PURITY
Frahm, A. W.,Knupp, G.
, p. 2633 - 2636 (2007/10/02)
Asymmetric reductive amination of racemic 2-substituted cyclohexanones (R= methyl, ethyl, phenyl, benzyl) using optically active 1-phenyl-ethylamines yields optically active cis-cyclohexanamines.
