99967-48-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99967-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,6 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99967-48:
(7*9)+(6*9)+(5*9)+(4*6)+(3*7)+(2*4)+(1*8)=223
223 % 10 = 3
So 99967-48-3 is a valid CAS Registry Number.

Highly enantioselective insertion of carbenoids into O-H bonds of phenols: An efficient approach to chiral α-aryloxycarboxylic esters

Chen, Chao,Zhu, Shou-Fei,Liu, Bin,Wang, Li-Xin,Zhou, Qi-Lin

, p. 12616 - 12617 (2007)

A highly efficient copper-catalyzed asymmetric carbenoid insertion into O-H bonds of phenols has been realized by using chiral spiro bisoxazoline ligands, affording α-aryloxypropionates and the related propionic acids in high yields with excellent enantiomeric excesses. Copyright
