133787-01-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133787-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133787-01:
(8*1)+(7*3)+(6*3)+(5*7)+(4*8)+(3*7)+(2*0)+(1*1)=136
136 % 10 = 6
So 133787-01-6 is a valid CAS Registry Number.

Asymmetric electrochemical oxidation of 1,2-diols, aminoalcohols, and?aminoaldehydes in the presence of chiral copper catalyst

Minato, Daishirou,Arimoto, Hitomi,Nagasue, Yoko,Demizu, Yosuke,Onomura, Osamu

, p. 6675 - 6683 (2008/12/20)

Asymmetric oxidation of 1,2-diols, aminoalcohols, and aminoaldehydes in the presence of copper(II) triflate and (R,R)-Ph-BOX was accomplished by electrochemical method using Br- as a mediator. This oxidation was applicable to kinetic resolution of racemic cis-cycloalkane-1,2-diols, aminoalcohols, and aminoaldehydes to afford optically active compounds with good to high enantioselectivity.
