Check Digit Verification of cas no

The CAS Registry Mumber 121906-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,0 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121906-87:
(8*1)+(7*2)+(6*1)+(5*9)+(4*0)+(3*6)+(2*8)+(1*7)=114
114 % 10 = 4
So 121906-87-4 is a valid CAS Registry Number.

A Convenient Enantioselective Synthesis of trans-2-Aryloxycyclohexan-1-ols Using Pig Liver Acetone Powder (PLAP) as Biocatalyst

Basavaiah, Deevi,Krishna, Peddinti Rama,Bharathi, Tirumala K.

, p. 439 - 454 (2007/10/02)

Pig liver acetone powder (PLAP) has been used as a biocatalyst for enantioselective hydrolysis of racemic trans-1-acetoxy-2-aryloxycyclohexanes to produce the resulting (R,R)-2-aryloxycyclohexan-1-ols upto >99percent enantiomeric purities. (R,R)-Selectivity in this hydrolysis of racemic trans-2-aryloxycyclohexyl acetates was explained on the basis of Jones' three dimensional active site-model.
